2009-12-01powerpc: Fix DEBUG_HIGHMEM build break from d4515646699Becky Bruce
Code was added to mm/higmem.c that depends on several kmap types that powerpc does not support. We add dummy invalid definitions for KM_NMI, KM_NM_PTE, and KM_IRQ_PTE. According to list discussion, this fix should not be needed anymore starting with 2.6.33. The code is commented to this effect so hopefully we will remember to remove this.

2009-11-30jffs2: Fix memory corruption in jffs2_read_inode_range()David Woodhouse
In 2.6.23 kernel, commit a32ea1e1f925399e0d81ca3f7394a44a6dafa12c ("Fix read/truncate race") fixed a race in the generic code, and as a side effect, now do_generic_file_read() can ask us to readpage() past the i_size. This seems to be correctly handled by the block routines (e.g. block_read_full_page() fills the page with zeroes in case if somebody is trying to read past the last inode's block). JFFS2 doesn't handle this; it assumes that it won't be asked to read pages which don't exist -- and thus that there will be at least _one_ valid 'frag' on the page it's being asked to read. It will fill any holes with the following memset: memset(buf, 0, min(end, frag->ofs + frag->size) - offset); When the 'closest smaller match' returned by jffs2_lookup_node_frag() is actually on a previous page and ends before 'offset', that results in: memset(buf, 0, <huge unsigned negative>); Hopefully, in most cases the corruption is fatal, and quickly causing random oopses, like this: root@10.0.0.4:~/ltp-fs-20090531# ./testcases/kernel/fs/ftest/ftest01 Unable to handle kernel paging request for data at address 0x00000008 Faulting instruction address: 0xc01cd980 Oops: Kernel access of bad area, sig: 11 [#1] [...] NIP [c01cd980] rb_insert_color+0x38/0x184 LR [c0043978] enqueue_hrtimer+0x88/0xc4 Call Trace: [c6c63b60] [c004f9a8] tick_sched_timer+0xa0/0xe4 (unreliable) [c6c63b80] [c0043978] enqueue_hrtimer+0x88/0xc4 [c6c63b90] [c0043a48] __run_hrtimer+0x94/0xbc [c6c63bb0] [c0044628] hrtimer_interrupt+0x140/0x2b8 [c6c63c10] [c000f8e8] timer_interrupt+0x13c/0x254 [c6c63c30] [c001352c] ret_from_except+0x0/0x14 --- Exception: 901 at memset+0x38/0x5c LR = jffs2_read_inode_range+0x144/0x17c [c6c63cf0] [00000000] (null) (unreliable) This patch fixes the issue, plus fixes all LTP tests on NAND/UBI with JFFS2 filesystem that were failing since 2.6.23 (seems like the bug above also broke the truncation).

2009-11-30mac80211: fix spurious delBA handlingJohannes Berg
Lennert Buytenhek noticed that delBA handling in mac80211 was broken and has remotely triggerable problems, some of which are due to some code shuffling I did that ended up changing the order in which things were done -- this was commit d75636ef9c1af224f1097941879d5a8db7cd04e5 Author: Johannes Berg <johannes@sipsolutions.net> Date: Tue Feb 10 21:25:53 2009 +0100 mac80211: RX aggregation: clean up stop session and other parts were already present in the original commit d92684e66091c0f0101819619b315b4bb8b5bcc5 Author: Ron Rindjunsky <ron.rindjunsky@intel.com> Date: Mon Jan 28 14:07:22 2008 +0200 mac80211: A-MPDU Tx add delBA from recipient support The first problem is that I moved a BUG_ON before various checks -- thereby making it possible to hit. As the comment indicates, the BUG_ON can be removed since the ampdu_action callback must already exist when the state is != IDLE. The second problem isn't easily exploitable but there's a race condition due to unconditionally setting the state to OPERATIONAL when a delBA frame is received, even when no aggregation session was ever initiated. All the drivers accept stopping the session even then, but that opens a race window where crashes could happen before the driver accepts it. Right now, a WARN_ON may happen with non-HT drivers, while the race opens only for HT drivers. For this case, there are two things necessary to fix it: 1) don't process spurious delBA frames, and be more careful about the session state; don't drop the lock 2) HT drivers need to be prepared to handle a session stop even before the session was really started -- this is true for all drivers (that support aggregation) but iwlwifi which can be fixed easily. The other HT drivers (ath9k and ar9170) are behaving properly already.

2009-11-29NET: smc91x: Fix irq flagsRussell King - ARM Linux
smc91x.h defines SMC_IRQ_FLAGS to be -1 when it wants the interrupt flags to be taken from the resource structure. However, d280ead changed this to checking for non-zero resource flags. Unfortunately, this means that on some platforms, we end up passing '-1' to request_irq rather than the desired result. Combine the two conditions into one so that the IRQ flags are taken from the resource if either SMC_IRQ_FLAGS is -1 or the resource flags specify an interrupt trigger. This restores network on at least the Versatile platform. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk> Acked-by: Eric Miao <eric.y.miao@gmail.com> Signed-off-by: David S.

2009-11-29r8169: restore mac addr in rtl8169_remove_one and rtl_shutdownIvan Vecera
The newer chipsets (all PCI-E) are known that they need full power cycle (AC or battery removal) to reset MAC address to a hardwired one. Previous patch to address this problem loads the original MAC address from EEPROM. But it brought other problem for which it is necessary to introduce a new module parameter. However, it might suffice to restore the initial MAC address before shutdown/reboot/kexec and when removing the module. Signed-off-by: Ivan Vecera <ivecera@redhat.com> Signed-off-by: David S.

2009-11-29ipv4: additional update of dev_net(dev) to struct *net in ip_fragment.c, ↵David Ford
NULL ptr OOPS ipv4 ip_frag_reasm(), fully replace 'dev_net(dev)' with 'net', defined previously patched into 2.6.29. Between 2.6.28.10 and 2.6.29, net/ipv4/ip_fragment.c was patched, changing from dev_net(dev) to container_of(...). Unfortunately the goto section (out_fail) on oversized packets inside ip_frag_reasm() didn't get touched up as well. Oversized IP packets cause a NULL pointer dereference and immediate hang. I discovered this running openvasd and my previous email on this is titled: NULL pointer dereference at 2.6.32-rc8:net/ipv4/ip_fragment.c:566 Signed-off-by: David Ford <david@blue-labs.org> Signed-off-by: David S.

2009-11-29e100: Use pci pool to work around GFP_ATOMIC order 5 memory allocation failureRoger Oksanen
pci_alloc_consistent uses GFP_ATOMIC allocation that may fail on some systems with limited memory (Bug #14265). pci_pool_alloc allows waiting with GFP_KERNEL.

2009-11-29PM: fix irq enable/disable in runtime PM codeAlan Stern
This patch (as1305) fixes a bug in the irq-enable settings and removes some related overhead in the runtime PM code. In __pm_runtime_resume(), within the scope of the original spin_lock_irq(), we know that irqs are disabled. There's no reason to go through a pair of enable/disable cycles when acquiring and releasing the parent's lock. In __pm_runtime_set_status(), irqs are already disabled when the parent's lock is acquired, and they must remain disabled when it is released.

2009-11-29sctp: on T3_RTX retransmit all the in-flight chunksAndrei Pelinescu-Onciul
When retransmitting due to T3 timeout, retransmit all the in-flight chunks for the corresponding transport/path, including chunks sent less then 1 rto ago. This is the correct behaviour according to rfc4960 section 6.3.3 E3 and "Note: Any DATA chunks that were sent to the address for which the T3-rtx timer expired but did not fit in one MTU (rule E3 above) should be marked for retransmission and sent as soon as cwnd allows (normally, when a SACK arrives). ". This fixes problems when more then one path is present and the T3 retransmission of the first chunk that timeouts stops the T3 timer for the initial active path, leaving all the other in-flight chunks waiting forever or until a new chunk is transmitted on the same path and timeouts (and this will happen only if the cwnd allows sending new chunks, but since cwnd was dropped to MTU by the timeout => it will wait until the first heartbeat). Example: 10 packets in flight, sent at 0.1 s intervals on the primary path. The primary path is down and the first packet timeouts. The first packet is retransmitted on another path, the T3 timer for the primary path is stopped and cwnd is set to MTU. All the other 9 in-flight packets will not be retransmitted (unless more new packets are sent on the primary path which depend on cwnd allowing it, and even in this case the 9 packets will be retransmitted only after a new packet timeouts which even in the best case would be more then RTO). This commit reverts d0ce92910bc04e107b2f3f2048f07e94f570035d and also removes the now unused transport->last_rto, introduced in b6157d8e03e1e780660a328f7183bcbfa4a93a19. p.s The problem is not only when multiple paths are there. It can happen in a single homed environment. If the application stops sending data, it possible to have a hung association.

2009-11-27V4L/DVB (13530): Fix wrong parameter order in memsetAlan Cox
Edwin Török found the following: In function ‘memset’, inlined from ‘ir_input_init’ at drivers/media/common/ir-functions.c:67: /home/edwin/builds/linux-2.6/arch/x86/include/asm/string_64.h:61: warning: call to ‘__warn_memset_zero_len’ declared with attribute warning: memset used with constant zero length parameter; this could be due to transposed parameters memset(ir->ir_codes, sizeof(ir->ir_codes), 0); In actual practice the only caller I can find happens to already have cleared the buffer before calling ir_input_init.
