| | * | | | [PATCH] bcm43xx: sysfs code cleanupMichael Buesch2006-04-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This cleans up the bcm43xx sysfs code and makes it compliant with the unwritten sysfs rules (at least I hope so).

| | * | | | [PATCH] softmac: fix spinlock recursion on reassocMichael Buesch2006-04-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes a spinlock recursion on receiving a reassoc request. On reassoc, the softmac calls back into the driver. This results in a driver lock recursion. This schedules the assoc workqueue, instead of calling it directly. Probably, we should defer the _whole_ management frame processing to a tasklet or workqueue, because it does several callbacks into the driver. That is dangerous. This fix should go into linus's tree, before 2.6.17 is released, because it is remote exploitable (DoS by crash). Signed-off-by: John W. Linville <linville@tuxdriver.com>

I personally disagree with this change and want it reverted. Patch for 2.6.17-rc1. Rationale : WIRELESS_EXT is an invisible option. Therefore, the only way for a user to enable it is via NET_RADIO. Some users need to do that for out-of-tree drivers. Therefore it should be mentionned in the title of the option. Rationale2 : the option just below is called "Wireless Extension API over RtNetlink". Some users may confuse this option for the main "Wireless Extension" option. Therefore reverting this change help disambiguate the relation between those two options.

Loss of sync due to scan requests also results in disassociation events sent to user space. This patch traps those two events; suppressing sync-loss on scan, and sending the correct association event on re-association notifications.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | AMD K7/K8 CPUs only save/restore the FOP/FIP/FDP x87 registers in FXSAVE when an exception is pending. This means the value leak through context switches and allow processes to observe some x87 instruction state of other processes. This was actually documented by AMD, but nobody recognized it as being different from Intel before. The fix first adds an optimization: instead of unconditionally calling FNCLEX after each FXSAVE test if ES is pending and skip it when not needed. Then do a x87 load from a kernel variable to clear FOP/FIP/FDP. This means other processes always will only see a constant value defined by the kernel in their FP state. I took some pain to make sure to chose a variable that's already in L1 during context switch to make the overhead of this low. Also alternative() is used to patch away the new code on CPUs who don't need it. Patch for both i386/x86-64. The problem was discovered originally by Jan Beulich. Richard Brunner provided the basic code for the workarounds, with contribution from Jan.

* | | | | | | [PATCH] sound: fix hang in mpu401_uart.cJon Masters2006-04-20

Eventually discovered after wine/cxoffice would constantly cause hard lockups on my desktop immediately after loading (emulating Windows too well). Turned out that I'd recently moved my sound cards around and using /dev/sequencer now talks to a sound card with a broken MPU. This second version changes -EFAULT to -EIO and frees open resources on error too. Test booted and seems to work ok.

The most simple fix is to clear the PEC bit after after every transaction. That's what this driver was doing up to 2.6.15 (inclusive). Thanks to Daniele Gaffuri for the very good report.
