ide: clear bmdma status in ide_intr() for ICHx controllers (revised #4)

2007-07-22T16:05:44+00:00

patch 1/2 (revised): - Fix drive->waiting_for_dma to work with CDB-intr devices. - Do the dma status clearing in ide_intr() and add a new hwif->ide_dma_clear_irq for Intel ICHx controllers. Revised per Alan, Sergei and Bart's advice. Patch against 2.6.20-rc6. Tested ok on my ICH4 and pdc20275 adapters. Please review/apply, thanks. Signed-off-by: Albert Lee Signed-off-by: Adrian Bunk

[NETPOLL]: Fix TX queue overflow in trapped mode.

2007-05-22T22:41:22+00:00

CONFIG_NETPOLL_TRAP causes the TX queue controls to be completely bypassed in the netpoll's "trapped" mode which easily causes overflows in the drivers with short TX queues (most notably, in 8139too with its 4-deep queue). So, make this option more sensible by making it only bypass the TX softirq wakeup.

[NETFILTER]: ip_nat_proto_gre: do not modify/corrupt GREv0 packets through NAT

2007-05-03T23:00:32+00:00

While porting some changes of the 2.6.21-rc7 pptp/proto_gre conntrack and nat modules to a 2.4.32 kernel I noticed that the gre_key function returns a wrong pointer to the GRE key of a version 0 packet thus corrupting the packet payload. The intended behaviour for GREv0 packets is to act like ip_conntrack_proto_generic/ip_nat_proto_unknown so I have ripped the offending functions (not used anymore) and modified the ip_nat_proto_gre modules to not touch version 0 (non PPTP) packets.

[IPV6]: Disallow RH0 by default (CVE-2007-2242)

2007-04-30T23:31:47+00:00

A security issue is emerging. Disallow Routing Header Type 0 by default as we have been doing for IPv4. This version already includes a fix for the original patch. Signed-off-by: YOSHIFUJI Hideaki Signed-off-by: Adrian Bunk

V4L: saa7146: Fix allocation of clipping memory

2007-04-13T20:58:25+00:00

Olaf Hering pointed out that SAA7146_CLIPPING_MEM would become very large for PAGE_SIZE > 4K. In fact, the number of clipping windows is limited to 16, and calculate_clipping_registers_rect() does not use more than 256 bytes. SAA7146_CLIPPING_MEM adjusted accordingly.

prevent timespec/timeval to ktime_t overflow

2007-04-08T22:03:30+00:00

Frank v. Waveren pointed out that on 64bit machines the timespec to ktime_t conversion might overflow. This is also true for timeval to time_t conversions. This breaks a "sleep inf" on 64bit machines. While a timespec/timeval with tx.sec = MAX_LONG is valid by specification the internal representation of ktime_t is based on nanoseconds. The conversion of seconds to nanoseconds overflows for seconds values >= (MAX_LONG / NSEC_PER_SEC). Check the seconds argument to the conversion and limit it to the maximum time which can be represented by ktime_t. Signed-off-by: Thomas Gleixner Signed-off-by: Adrian Bunk

[IFB]: Fix crash on input device removal

2007-04-03T02:03:55+00:00

The input_device pointer is not refcounted, which means the device may disappear while packets are queued, causing a crash when ifb passes packets with a stale skb->dev pointer to netif_rx(). Fix by storing the interface index instead and do a lookup where neccessary. Signed-off-by: Patrick McHardy Signed-off-by: Adrian Bunk
