We already use them for openat() and friends, but fstat() also wants to be able to use O_PATH file descriptors. This should make it more directly comparable to the O_SEARCH of Solaris. Note that you could already do the same thing with "fstatat()" and an empty path, but just doing "fstat()" directly is simpler and faster, so there is no reason not to just allow it directly. See also commit 332a2e12, which did the same thing for fchdir, for the same reasons.

One from before 3.6-rc1 and two from the new CPU hotplug code. Kudos to Lai for discovering all of them and providing fixes. * Atomicity bug when clearing a flag and setting another. The two operation should have been atomic but wasn't. This bug has existed for a long time but is unlikely to have actually happened. Fix is safe. Marked for -stable. * If CPU hotplug cycles happen back-to-back before workers finish the previous cycle, the states could get out of sync and it could get stuck. Fixed by waiting for workers to complete before finishing hotplug cycle. * While CPU hotplug is in progress, idle workers could be depleted which can then lead to deadlock. I think both happening together is highly unlikely but still better to fix it and the fix isn't too scary. There's another workqueue related regression which reported a few days ago: https://bugzilla.kernel.org/show_bug.cgi?id=47301 It's a bit of head scratcher but there is a semi-reliable reproduce case, so I'm hoping to resolve it soonish." * 'for-3.6-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq: workqueue: fix possible idle worker depletion across CPU hotplug workqueue: restore POOL_MANAGING_WORKERS workqueue: fix possible deadlock in idle worker rebinding workqueue: move WORKER_REBIND clearing in rebind_workers() to the end of the function workqueue: UNBOUND -> REBIND morphing in rebind_workers() should be atomic

The authenc code doesn't deal with zero-length associated data correctly and ends up constructing a zero-length sg entry which causes a crash when it's fed into the crypto system. This patch fixes this by avoiding the code-path that triggers the SG construction if we have no associated data. This isn't the most optimal fix as it means that we'll end up using the fallback code-path even when we could still execute the digest function. However, this isn't a big deal as nobody but the test path would supply zero-length associated data.

Commit 1f2bfbd0 ("kbuild: link of vmlinux moved to a script") introduced in v3.5-rc1 broke kallsyms on architectures which have symbol prefixes. The --symbol-prefix argument used to be added to the KALLSYMS command line from the architecture Makefile, however this isn't picked up by the new scripts/link-vmlinux.sh. This resulted in symbols like kallsyms_addresses being added which weren't correctly overriding the weak symbols such as _kallsyms_addresses. These could then trigger BUG_ONs in kallsyms code. This is fixed by removing the KALLSYMS addition from the architecture Makefile, and using CONFIG_SYMBOL_PREFIX in the link-vmlinux.sh script to determine whether to add the --symbol-prefix argument.

由 Lai Jiangshan 提交于
To simplify both normal and CPU hotplug paths, worker management is prevented while CPU hoplug is in progress. This is achieved by CPU hotplug holding the same exclusion mechanism used by workers to ensure there's only one manager per pool. If someone else seems to be performing the manager role, workers proceed to execute work items. CPU hotplug using the same mechanism can lead to idle worker depletion because all workers could proceed to execute work items while CPU hotplug is in progress and CPU hotplug itself wouldn't actually perform the worker management duty - it doesn't guarantee that there's an idle worker left when it releases management. This idle worker depletion, under extreme circumstances, can break forward-progress guarantee and thus lead to deadlock. This patch fixes the bug by using separate mechanisms for manager exclusion among workers and hotplug exclusion. For manager exclusion, POOL_MANAGING_WORKERS which was restored by the previous patch is used. pool->manager_mutex is now only used for exclusion between the elected manager and CPU hotplug. The elected manager won't proceed without holding pool->manager_mutex. This ensures that the worker which won the manager position can't skip managing while CPU hotplug is in progress. It will block on manager_mutex and perform management after CPU hotplug is complete. Note that hotplug may happen while waiting for manager_mutex. A manager isn't either on idle or busy list and thus the hoplug code can't unbind/rebind it. Make the manager handle its own un/rebinding. tj: Updated comment and description.

This patch restores POOL_MANAGING_WORKERS which was replaced by pool->manager_mutex by 60373152 "workqueue: use mutex for global_cwq manager exclusion". There's a subtle idle worker depletion bug across CPU hotplug events and we need to distinguish an actual manager and CPU hotplug preventing management. POOL_MANAGING_WORKERS will be used for the former and manager_mutex the later. This patch just lays POOL_MANAGING_WORKERS on top of the existing manager_mutex and doesn't introduce any synchronization changes. The next patch will update it. Note that this patch fixes a non-critical anomaly where too_many_workers() may return %true spuriously while CPU hotplug is in progress. While the issue could schedule idle timer spuriously, it didn't trigger any actual misbehavior. tj: Rewrote patch description.

snd_hda_codec_reset() calls restore_pincfgs() where the codec is powered up again, which eventually tries to resume and initialize via the callbacks of the codec. However, it's the place just after codec free callback, thus no codec callbacks should be called after that. On a codec like CS4206, it results in Oops due to the access in init callback. This patch fixes the issue by clearing the codec callbacks properly after freeing codec.

If kernel is compiled with CONFIG_PROVE_LOCKING the validator raises an error when a multiplexer is removed via sysfs and sub-clients are connected to it. This is a false positive. Documentation/lockdep-design.txt recommends to handle this via calls to mutex_lock_nested(). Based on an earlier fix from Michael Lawnick. Note that the extra code resolves to nothing unless CONFIG_DEBUG_LOCK_ALLOC=y. Signed-off-by: NJean Delvare <khali@linux-fr.org> Cc: Michael Lawnick <ml.lawnick@gmx.de>

This patch adds config I2C_DESIGNWARE_CORE in Kconfig, and let I2C_DESIGNWARE_PLATFORM and I2C_DESIGNWARE_PCI select I2C_DESIGNWARE_CORE. Because both I2C_DESIGNWARE_PLATFORM and I2C_DESIGNWARE_PCI can be built as built-in or module, we also need to export the functions in i2c-designware-core. This fixes below build error when CONFIG_I2C_DESIGNWARE_PLATFORM=y && CONFIG_I2C_DESIGNWARE_PCI=y: LD drivers/i2c/busses/built-in.o drivers/i2c/busses/i2c-designware-pci.o: In function `i2c_dw_clear_int': i2c-designware-core.c:(.text+0xa10): multiple definition of `i2c_dw_clear_int' drivers/i2c/busses/i2c-designware-platform.o:i2c-designware-platdrv.c:(.text+0x928): first defined here drivers/i2c/busses/i2c-designware-pci.o: In function `i2c_dw_init': i2c-designware-core.c:(.text+0x178): multiple definition of `i2c_dw_init' drivers/i2c/busses/i2c-designware-platform.o:i2c-designware-platdrv.c:(.text+0x90): first defined here drivers/i2c/busses/i2c-designware-pci.o: In function `dw_readl': i2c-designware-core.c:(.text+0xe8): multiple definition of `dw_readl' drivers/i2c/busses/i2c-designware-platform.o:i2c-designware-platdrv.c:(.text+0x0): first defined here drivers/i2c/busses/i2c-designware-pci.o: In function `i2c_dw_isr': i2c-designware-core.c:(.text+0x724): multiple definition of `i2c_dw_isr' drivers/i2c/busses/i2c-designware-platform.o:i2c-designware-platdrv.c:(.text+0x63c): first defined here drivers/i2c/busses/i2c-designware-pci.o: In function `i2c_dw_xfer': i2c-designware-core.c:(.text+0x4b0): multiple definition of `i2c_dw_xfer' drivers/i2c/busses/i2c-designware-platform.o:i2c-designware-platdrv.c:(.text+0x3c8): first defined here drivers/i2c/busses/i2c-designware-pci.o: In function `i2c_dw_is_enabled': i2c-designware-core.c:(.text+0x9d4): multiple definition of `i2c_dw_is_enabled' drivers/i2c/busses/i2c-designware-platform.o:i2c-designware-platdrv.c:(.text+0x8ec): first defined here drivers/i2c/busses/i2c-designware-pci.o: In function `dw_writel': i2c-designware-core.c:(.text+0x124): multiple definition of `dw_writel' drivers/i2c/busses/i2c-designware-platform.o:i2c-designware-platdrv.c:(.text+0x3c): first defined here drivers/i2c/busses/i2c-designware-pci.o: In function `i2c_dw_xfer_msg': i2c-designware-core.c:(.text+0x2e8): multiple definition of `i2c_dw_xfer_msg' drivers/i2c/busses/i2c-designware-platform.o:i2c-designware-platdrv.c:(.text+0x200): first defined here drivers/i2c/busses/i2c-designware-pci.o: In function `i2c_dw_enable': i2c-designware-core.c:(.text+0x9c8): multiple definition of `i2c_dw_enable' drivers/i2c/busses/i2c-designware-platform.o:i2c-designware-platdrv.c:(.text+0x8e0): first defined here drivers/i2c/busses/i2c-designware-pci.o: In function `i2c_dw_read_comp_param': i2c-designware-core.c:(.text+0xa24): multiple definition of `i2c_dw_read_comp_param' drivers/i2c/busses/i2c-designware-platform.o:i2c-designware-platdrv.c:(.text+0x93c): first defined here drivers/i2c/busses/i2c-designware-pci.o: In function `i2c_dw_disable': i2c-designware-core.c:(.text+0x9dc): multiple definition of `i2c_dw_disable' drivers/i2c/busses/i2c-designware-platform.o:i2c-designware-platdrv.c:(.text+0x8f4): first defined here drivers/i2c/busses/i2c-designware-pci.o: In function `i2c_dw_func': i2c-designware-core.c:(.text+0x710): multiple definition of `i2c_dw_func' drivers/i2c/busses/i2c-designware-platform.o:i2c-designware-platdrv.c:(.text+0x628): first defined here drivers/i2c/busses/i2c-designware-pci.o: In function `i2c_dw_disable_int': i2c-designware-core.c:(.text+0xa18): multiple definition of `i2c_dw_disable_int' drivers/i2c/busses/i2c-designware-platform.o:i2c-designware-platdrv.c:(.text+0x930): first defined here make[3]: *** [drivers/i2c/busses/built-in.o] Error 1 make[2]: *** [drivers/i2c/busses] Error 2 make[1]: *** [drivers/i2c] Error 2 make: *** [drivers] Error 2 Signed-off-by: NAxel Lin <axel.lin@gmail.com> Signed-off-by: NJean Delvare <khali@linux-fr.org> Tested-by: NJiri Slaby <jslaby@suse.cz> Cc: stable@vger.kernel.org [3.2+]
