From 1396adc3c2bdc556d4cdd1cf107aa0b6d59fbb1e Mon Sep 17 00:00:00 2001 From: "H. Peter Anvin" Date: Mon, 1 Oct 2012 14:34:42 -0700 Subject: [PATCH 001/257] x86, suspend: Correct the restore of CR4, EFER; skip computing EFLAGS.ID The patch: 73201dbe x86, suspend: On wakeup always initialize cr4 and EFER ... was incorrectly committed in an intermediate (unfinished) form. - We need to test CF, not ZF, for a bit test with btl. - We don't actually need to compute the existence of EFLAGS.ID, since we set a flag at suspend time if CR4 should be restored.

Ext3 has the same non initialized variable, but, in any case it will be initialized by ext3_get_blocks_handle(), which will avoid the bug to be triggered, but, the non-initialized variable by htree_dirblock_to_tree() is still a bug.

Focused on directory blocks, a NULL value returned from ext3_bread() means a hole, which cannot exist into a directory inode. It can pass undetected after a fix in an uninitialized error variable. The (now) initialized variable into ext3_getblk() may lead to a zero'ed return value of ext3_bread() to its callers, which can make the caller do not detect the hole in the directory inode. This patch creates a new wrapper function ext3_dir_bread() which checks for holes properly, reports error, and returns EIO in that case.

This patch changes it to be set in 3D_CHICKEN3, where it belongs. The game "Dante" demonstrates random clipping issues when guardband clipping is enabled and bit 5 of 3D_CHICKEN3 isn't set.

In init/main.c, we issue: kernel_thread(kernel_init, NULL, CLONE_FS | CLONE_SIGHAND); This creates a new thread, which falls through to the ret_from_fork assembly, with r4 set NULL and r5 set to kernel_init. You can see this in your oops dump register set - r5 is 0xc0344555, which is the address of kernel_init plus 1 which marks the function as Thumb code. Now, let's look at this code a little closer - this is what the disassembly looks like: c000d180 : c000d180: f03a fe08 bl c0047d94 c000d184: 2d00 cmp r5, #0 c000d186: bf1e ittt ne c000d188: 4620 movne r0, r4 c000d18a: 46fe movne lr, pc <-- XXXXXXX c000d18c: 46af movne pc, r5 c000d18e: 46e9 mov r9, sp c000d190: ea4f 3959 mov.w r9, r9, lsr #13 c000d194: ea4f 3949 mov.w r9, r9, lsl #13 c000d198: e7c8 b.n c000d12c c000d19a: bf00 nop c000d19c: f3af 8000 nop.w This code was introduced in 9fff2fa0db911 (arm: switch to saner kernel_execve() semantics). I have marked one instruction, and it's the significant one - I'll come back to that later. Eventually, having had a successful call to kernel_execve(), kernel_init() returns zero. In returning, it uses the value in 'lr' which was set by the instruction I marked above. Unfortunately, this causes lr to contain 0xc000d18e - an even address. This switches the ISA to ARM on return but with a non word aligned PC value. So, what do we end up executing? Well, not the instructions above - yes the opcodes, but they don't mean the same thing in ARM mode. In ARM mode, it looks like this instead: c000d18c: 46e946af strbtmi r4, [r9], pc, lsr #13 c000d190: 3959ea4f ldmdbcc r9, {r0, r1, r2, r3, r6, r9, fp, sp, lr, pc}^ c000d194: 3949ea4f stmdbcc r9, {r0, r1, r2, r3, r6, r9, fp, sp, lr, pc}^ c000d198: bf00e7c8 svclt 0x0000e7c8 c000d19c: 8000f3af andhi pc, r0, pc, lsr #7 c000d1a0: e88db092 stm sp, {r1, r4, r7, ip, sp, pc} c000d1a4: 46e81fff ; instruction: 0x46e81fff c000d1a8: 8a00f3ef bhi 0xc004a16c c000d1ac: 0a0cf08a beq 0xc03493dc I have included more above, because it's relevant. The PSR flags which we can see in the oops dump are nZCv, so Z and C are set. All the above ARM instructions are not executed, except for two. c000d1a0, which has no writeback, and writes below the current stack pointer (and that data is lost when we take the next exception.) The other instruction which is executed is c000d1ac, which takes us to... 0xc03493dc. However, remember that bit 1 of the PC got set. So that makes the PC value 0xc03493de. And that value is the value we find in the oops dump for PC. What is the instruction here when interpreted in ARM mode? 0: f71e150c ; instruction: 0xf71e150c and there we have our undefined instruction (remember that the 'never' condition code, 0xf, has been deprecated and is now always executed as it is now being used for additional instructions.) This path also nicely explains the state of the stack we see in the oops dump too. The above is a consistent and sane story for how we got to the oops dump, which all stems from the instruction at 0xc000d18a being wrong.

It especially cannot have the same live AR windows as the parent, otherwise it will overwrite the parent stack on overflow, likely causing corruption. (and so it did...)

Filippov Date: Mon, 15 Oct 2012 03:55:41 +0400 Subject: [PATCH 096/257] xtensa: Use Kbuild infrastructure to handle asm-generic headers Use Kbuild infrastructure to handle the asm-generic headers and

This either results in guest memory corruption and or the hardware faulting and 'crashing' the virtual machine. Therefore we have to disable PEBS on VT-x enter and re-enable on VT-x exit, enforcing a strict exclude_guest. AMB IBS does work but doesn't currently support exclude_* at all, setting an exclude_* bit will make it fail." This patch handles userspace perf command, setting the exclude_guest attribute if precise mode is requested, but only if a user has not specified a request for guest or host only profiling (G or H attribute). Kernel side AMD currently ignores all exclude_* bits, so there is no impact to existing IBS code paths. Robert Richter has a patch where IBS code will return EINVAL if an exclude_* bit is set. When this goes in it means use of :p on AMD with IBS will first fail with EINVAL (because exclude_guest will be set). Then the existing fallback code within perf will unset exclude_guest and try again. The second attempt will succeed if the CPU supports IBS profiling.

There's no problem with assigning it if the pevent is NULL, as the event->pevent would be NULL without the assignment. But function parsing handlers may be assigned to the pevent handler to help in parsing the event. If there's no pevent then there would not be any function handlers, but if the pevent isn't assigned first before parsing the event, it wont honor the function handlers that were assigned. Worse yet, the current code crashes if an event has a function that it tries to parse. For example: # perf record -e scsi:scsi_dispatch_cmd_timeout Segmentation fault (core dumped) This happens because the scsi_dispatch_cmd_timeout event format has the following: scsi_trace_parse_cdb(p, __get_dynamic_array(cmnd), REC->cmd_len) which hasn't been defined by the pevent code.

It uses attach, disconnect, and release routines to carry out actions that should be handled by port_probe and port_remove routines, because they access port-specific data. The bug causes an oops when the device in unplugged, because the private data for each port structure now gets erased when the port is unbound from the driver, resulting in a null-pointer dereference.

To do so, it needs to obtain the rtnl lock first, as the interface configuration is changed. If another process tries to modify an interface setting at the same time, that process can obtain the rtnl lock first, but the respective callback in the qeth driver will block until recovery has completed - which cannot happen since the calling process already obtained it. In one particular case, the bonding driver acquired the rtnl lock to modify the card's MAC address, while the recovery failed at the same time due to the card being removed. Hence qeth_l2_set_mac_address (implicitly holding the rtnl lock) was waiting on qeth_l2_recover, which deadlocked when waiting on the rtnl lock. This patch uses rtnl_trylock instead of rtnl_lock in the recovery thread. If the lock cannot be obtained, the interface will be left up, but the card state remains in CARD_STATE_RECOVER, which will prevent any further activities on the card.

There was a serious disconnect in the logic happening in sparc_pmu_disable_event() vs. sparc_pmu_enable_event(). Event disable is implemented by programming a NOP event into the PCR. However, event enable was not reversing this operation. Instead, it was setting the User/Priv/Hypervisor trace enable bits. That's not sparc_pmu_enable_event()'s job, that's what sparc_pmu_enable() and sparc_pmu_disable() do . The intent of sparc_pmu_enable_event() is clear, since it first clear out the event type encoding field. So fix this by OR'ing in the event encoding rather than the trace enable bits.

This causes a compile failure due to conflicting declarations and definitions of the functions. It turns out that the generic definitions in arch/mips/lib/delay.c also conflict. Proposed fix: Declare the functions to take unsigned long parameters just like asm-generic (and x86) does. Update __delay to agree (__ndelay and __udelay need no change). Bonus: Get rid of 'inline' from __delay() definition, as it is globally visible, and the compiler should be making this decision itself (it does in fact inline the function without being told to).

This happens because mpol_to_str() may return an error the stack-allocated buffer is then printed without ever being stored. There are two possible error conditions in mpol_to_str(): - if the buffer allocated is insufficient for the string to be stored, and - if the mempolicy has an invalid mode. The first error condition is not triggered in any of the callers to mpol_to_str(): at least 50 bytes is always allocated on the stack and this is sufficient for the string to be written. A future patch should convert this into BUILD_BUG_ON() since we know the maximum strlen possible, but that's not -rc material. The second error condition is possible if a race occurs in dropping a reference to a task's mempolicy causing it to be freed during the read(). The slab poison value is then used for the mode and mpol_to_str() returns -EINVAL. This race is only possible because get_vma_policy() believes that mm->mmap_sem protects task->mempolicy, which isn't true. The exit path does not hold mm->mmap_sem when dropping the reference or setting task->mempolicy to NULL: it uses task_lock(task) instead. Thus, it's required for the caller of a task mempolicy to hold task_lock(task) while grabbing the mempolicy and reading it. Callers with a vma policy store their mempolicy earlier and can simply increment the reference count so it's guaranteed not to be freed.

They used to have only header-y lines in them and those have now moved to the Kbuild files in the corresponding uapi/ directories. Possibly these should not be removed but rather have a comment inserted to say they are intentionally left blank. This would make it easier to add generated header lines in future without having to restore the infrastructure. Note that at this point not all the UAPI disintegration parts have been merged, so it is likely that more empty Kbuild files will turn up. It is probably necessary to make the files non-empty to prevent the patch program from automatically deleting them when it reduces them to nothing.

Possibly they should be just deleted, but it's possible that they'll acquire generic-y or genhdr-y lines in future, so I'm keeping them around for the moment. Note that MIPS will compile happily if the file is deleted instead. I haven't tested TILE, but I suspect it will be the same there.

Earlier without cpuidle framework on pseries, the native arch idle routine comprised of both snooze and nap states. smt_snooze_delay variable was used to delay the idle process entry to deeper idle state like nap. With the coming of cpuidle, this arch specific idle was replaced by two different idle routines, one for supporting snooze and other for nap. This enabled addition of more low level idle states on pseries in the future. On adopting the generic cpuidle framework for POWER systems, the decision of which idle state to choose from, given a predicted idle time is taken by the menu governor based on target_residency and exit_latency of the idle states. target_residency is the minimum time to be resident in that idle state. Exit_latency is time taken to exit out of idle state. Deeper the idle state, both the target residency and exit latency would be higher. In the current design, smt_snooze_delay is used as target_residency for the snooze state which is incorrect, as it is not the minimum but the maximum duration to be in snooze state. This would result in the governor in taking bad decision, as presently target_residency of nap < target_residency of snooze inspite of nap being deeper idle state. This patch aims to fix this problem by replacing the smt_snooze_delay loop in snooze state, with the need_resched() as the governor is aware of entry and exit of various idle transitions based on which next idle time prediction. The governor is intelligent enough to determine the idle state the needs to be transitioned to and maintains a whole of heuristics including io load, previous idle states predictions etc for the same, based on which idle state entry decision is taken. With this fix, of setting target_residency of snooze to 0 nap to smt_snooze_delay if the predicted idle time is less than smt_snooze_delay (target_residency of nap) value governor would pick snooze state, else nap. This adhers to the previous native idle design.

The same logic has been inherited in AArch64. The x0 register is overridden by the sys_execve() return value so it's always zero on success. The x1 and x2 registers are ignored by AArch64 and EABI AArch32 applications, so we can safely remove the register setting for both native and compat user space. This also fixes a potential fault with the kernel accessing user space stack directly.

This patch changes the control register setting so that disabled breakpoints are treated as HW_BREAKPOINT_EMPTY and no further sanity-checking is required.

If the name passed to simple_xattr_remove() does not exist in the list of xattrs, then it is possible to call kfree(new_xattr) when new_xattr is actually initialized to itself on the stack via uninitialized_var(). This causes a BUG() since the memory was not allocated via the slab allocator and was not bypassed through to the page allocator because it was too large. Initialize the local variable to NULL so the kfree() never takes place.

However, this info is not of any importance to userspace - it should rather get the actual error count it has been thresholded already from MCi_STATUS[38:52]. So drop this before it becomes a used interface (good thing we caught this early in 3.7-rc1, right after the merge window closed). Cc: Naveen N.

That commit had multiple bugs: - using "${#VARIABLE}" to get the number of characters in a shell variable may look clever, but it's locale-dependent: it returns the number of *characters*, not bytes. And we do need bytes. So don't use "${#..}" expansion, do the stupid "wc -c" thing instead (where "c" stands for "bytes", not "characters", despite the letter. - Rusty had confused "siglen" and "signerlen", and his conversion didn't set "signerlen" at all, and incorrectly set "siglen" to the size of the signer, not the size of the signature. End result: the modified sign-file script did create something that superficially *looked* like a signature, but didn't actually work at all, and would fail the signature check. Oops. Tssk, tssk, Rusty. But Rusty was definitely right that this whole thing should be rewritten in perl by somebody who has the perl-fu to do so. That is not me, though - I'm just doing an emergency fix for the shell script.

It sometimes accesses task->mempolicy which can be freed without mmap_sem and numa_maps can show some garbage while scanning. This patch tries to take reference count of task->mempolicy at reading numa_maps before calling get_vma_policy(). By this, task->mempolicy will not be freed until numa_maps reaches its end. V2->v3 - updated comments to be more verbose. - removed task_lock() in numa_maps code. V1->V2 - access task->mempolicy only once and remember it. Becase kernel/exit.c can overwrite it.

This allows module_sig_check() to be made simpler and faster by the elimination of the search for the magic string. Instead we just need to do a single memcmp(). This works because at the end of the signature data there is the fixed-length signature information block. This block then falls immediately prior to the magic number. From the contents of the information block, it is trivial to calculate the size of the signature data and thus the size of the actual module data.
