2008-10-03e1000e: Fix incorrect debug warningLinus Torvalds
Doing 'WARN_ON(preempt_count())' was horribly horribly wrong, and would cause tons of warnings at bootup if PREEMPT was enabled because the initcalls currently run with the kernel lock, which increments the preempt count. At the same time, the warning was also insufficient, since it didn't check that interrupts were enabled. The proper debug function to use for something that can sleep and wants a warning if it's called in the wrong context is 'might_sleep()'.

2008-10-02e1000e: do not ever sleep in interrupt contextJesse Brandeburg
e1000e was apparently calling two functions that attempted to reserve the SWFLAG bit for exclusive (to hardware and firmware) access to the PHY and NVM (aka eeprom).

2008-09-18bnx2: Promote vector field in bnx2_irq structure from u16 to unsigned intBenjamin Li
The bnx2 driver stores/uses the irq value from the pci_dev internally. But when it stores the irq value, it has been performing an integer demotion. Because of the recent changes made to arch/x86/kernel/io_apic.c, the new method in creating the irq value (using build_irq_for_pci_dev()) has exposed this bug on x86 systems. Because of this demotion when calling request_irq() from bnx2_request_irq(), the driver would get a return code of -EINVAL. This is because the kernel could not find the requested irq descriptor. By storing the irq value properly, the kernel can find the correct irq descriptor and the bnx2 driver can operate normally.

The allocated RX buffer size was 64 bytes bigger than the PCI mapped size with no good reason. If the packet was actually using the buffer up to its limit and if the last 64 bytes of the buffer crossed 4KB boundary then an unmapped PCI page was accessed. The fix is to use only one parameter for the buffer size - there is no need to differentiate between the buffer size and the PCI mapping size since the extra 64 bytes can actually be used by the FW to align the Ethernet payload to 64 bytes.

This patch is a W/A for the TSF sync issue in IBSS merging. HW is not capable to sync TSF (it's constantly little behind). This creates constant IBSS merging upon reception of each beacon, adding and removing station which in turn creates above 50% packet loss and thus dramatically degrade the throughput. The W/A simply stops the driver from declaring it has a reliable TSF value and thus eliminates IBSS merging.

2008-09-02ath9: Fix ath_rx_flush_tid() for IRQs disabled kernel warning message.Senthil Balasubramanian
This patch addresses an issue with the locking order. ath_rx_flush_tid() uses spin_lock/unlock_bh when IRQs are disabled in sta_notify by mac80211. As node clean up is still pending with ath9k and this problematic portion of the code is expected to change anyway, thinking of a proper fix may not be worthwhile. So having this interim fix helps the users to get rid of the kernel warning message. Pasted the kernel warning message for reference. kernel: ath0: No ProbeResp from current AP 00:1b:11:60:7a:3d - assume out of range kernel: ------------[ cut here ]------------ kernel: WARNING: at kernel/softirq.c:136 local_bh_enable+0x3c/0xab() kernel: Pid: 1029, comm: ath9k Not tainted 2.6.27-rc4-wt-w1fi-wl kernel: kernel: Call Trace: kernel: [<ffffffff802278d8>] warn_on_slowpath+0x51/0x77 kernel: [<ffffffff80224c51>] check_preempt_wakeup+0xf3/0x123 kernel: [<ffffffff80239658>] autoremove_wake_function+0x9/0x2e kernel: [<ffffffff8022c281>] local_bh_enable+0x3c/0xab kernel: [<ffffffffa01ab75a>] ath_rx_node_cleanup+0x38/0x6e [ath9k] kernel: [<ffffffffa01b2280>] ath_node_detach+0x3b/0xb6 [ath9k] kernel: [<ffffffffa01ab09f>] ath9k_sta_notify+0x12b/0x165 [ath9k] kernel: [<ffffffff802366cf>] queue_work+0x1d/0x49 kernel: [<ffffffffa018c3fc>] add_todo+0x70/0x99 [mac80211] kernel: [<ffffffffa017de76>] __sta_info_unlink+0x16b/0x19e [mac80211] kernel: [<ffffffffa017e6ed>] sta_info_unlink+0x18/0x43 [mac80211] kernel: [<ffffffffa0182732>] ieee80211_associated+0xaa/0x16d [mac80211] kernel: [<ffffffffa0184a1a>] ieee80211_sta_work+0x4fb/0x6b4 [mac80211] kernel: [<ffffffff80469c58>] thread_return+0x30/0xa9 kernel: [<ffffffffa018451f>] ieee80211_sta_work+0x0/0x6b4 [mac80211] kernel: [<ffffffff802362c2>] run_workqueue+0xb1/0x17a kernel: [<ffffffff80236be9>] worker_thread+0xd0/0xdb kernel: [<ffffffff8023964f>] autoremove_wake_function+0x0/0x2e kernel: [<ffffffff80236b19>] worker_thread+0x0/0xdb kernel: [<ffffffff8023954a>] kthread+0x47/0x75 kernel: [<ffffffff80223121>] schedule_tail+0x18/0x50 kernel: [<ffffffff8020bc49>] child_rip+0xa/0x11 kernel: [<ffffffff80239503>] kthread+0x0/0x75 kernel: [<ffffffff8020bc3f>] child_rip+0x0/0x11 kernel: kernel: ---[ end trace e9bb5da661055827 ]--- Signed-off-by: Senthil Balasubramanian <senthilkumar@atheros.com> Signed-off-by: John W.

2008-09-02ath9k: Incorrect key used when group and pairwise ciphers are different.Senthil Balasubramanian
Updating sc_keytype multiple times when groupwise and pairwise ciphers are different results in incorrect pairwise key type assumed for TX control and normal ping fails. This works fine for cases where both groupwise and pairwise ciphers are same. Also use mac80211 provided enums for key length calculation.

2008-09-02rt2x00: Compiler warning unmasked by fix of BUILD_BUG_ONBoaz Harrosh
A "Set" to a sign-bit in an "&" operation causes a compiler warning. Make calculations unsigned. [ The warning was masked by the old definition of BUILD_BUG_ON() ] Also remove __builtin_constant_p from FIELD_CHECK since BUILD_BUG_ON no longer permits non-const values.

The leak in if_cs_prog_helper() is obvious. It looks a bit as if not freeing "fw" in if_cs_prog_real() was done intentionally, but I'm not seeing why it shouldn't be freed.

2008-09-02orinoco: Multicast to the specified addressesDavid Kilroy
When multicasting the driver sets the number of group addresses using the count from the previous set multicast command. In general this means you have to set the multicast addresses twice to get the behaviour you want. If we were multicasting, and reduce the number of addresses we are multicasting to, then the driver would write uninitialised data from the stack into the group addresses to multicast to. Only write the multicast addresses we have specifically set. Signed-off-by: David Kilroy <kilroyd@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
