Unused indices which are ignored while walking must still be counted to avoid dumping the same index twice. Signed-off-by: Thomas Graf <tgraf@suug.ch> Signed-off-by: David S. Miller <davem@davemloft.net>

2005-05-30[NETFILTER]: Fix deadlock with ip_queue and tcp local input path.Harald Welte
When we have ip_queue being used from LOCAL_IN, then we end up with a situation where the verdicts coming back from userspace traverse the TCP input path from syscall context. While this seems to work most of the time, there's an ugly deadlock: syscall context is interrupted by the timer interrupt. When the timer interrupt leaves, the timer softirq get's scheduled and calls tcp_delack_timer() and alike. They themselves do bh_lock_sock(sk), which is already held from somewhere else -> boom. I've now tested the suggested solution by Patrick McHardy and Herbert Xu to simply use local_bh_{en,dis}able(). Signed-off-by: Harald Welte <laforge@netfilter.org> Signed-off-by: David S.

2005-05-29[NET]: Add is_multicast_ether_addr() in include/linux/etherdevice.hMichael Ellerman
This patch adds is_multicast_ether_addr() to go along with is_valid_ether_addr() and friends. It then changes is_valid_ether_addr() to use the new macro, and fixes up the comment on that function to move implementation details out of the API doco.

2005-05-29[TG3]: Fix bug in tg3_load_firmware_cpuMichael Chan
Add tg3_nvram_lock() and tg3_nvram_unlock() calls around tg3_halt_cpu(). It is possible that the bootcode may be loading code from nvram during this call and stopping the cpu without getting the lock may cause uncompleted nvram data to be left in the nvram data register.

2005-05-29[BRIDGE]: receive path optimizationStephen Hemminger
This improves the bridge local receive path by avoiding going through another softirq. The bridge receive path is already being called from a netif_receive_skb() there is no point in going through another receiveq round trip. Recursion is limited because bridge can never be a port of a bridge so handle_bridge() always returns. Signed-off-by: David S. Miller <davem@davemloft.net>
2005-05-29[BRIDGE]: prevent bad forwarding table updatesStephen Hemminger

2005-05-28[PATCH] ppc32: MPC834x BCSR_SIZE too small for use in a BAT.Kumar Gala
The call to io_block_mapping was creating an invalid BAT entry because the value of BCSR_SIZE (32K) is too small to be used in a BAT (128K min). This change removes the io_block_mapping call since these registers can easily be mapped using ioremap at the point of use.

2005-05-28[PATCH] ppc32: Simplified load string emulation error checkingKumar Gala
The error checking for emulation of load string instructions was overly generous and would cause certain valid forms of the instructions to be treated as illegal. We drop the range checking since the architecture allows this to be boundedly undefined. Tests on CPUs that support these instructions appear not do cause illegal instruction traps on range errors and just allow the execution to occur. Thanks to Kim Phillips for debugging this and figuring out what real HW was doing.

2005-05-28[PATCH] ppc32: Support for 82xx PQII on-chip PCI bridgeVitaly Bordug
This patch adds on-chip PCI bridge support for the PQ2 family. The incomplete existent code is updated with interrupt handling stuff and board-specific bits for 8272ADS and PQ2FADS; the related files were renamed (from m8260_pci to m82xx_pci) to be of more generic fashion. This is tested with 8266ADS and 8272ADS, should work on PQ2FADS as well.

2005-05-28[PATCH] uml: remove jail mode + other leftoversPaolo 'Blaisorblade' Giarrusso
This var is currently useless, as it's apparent from reading the code. Until 2.6.11 it was used in some code related to jail mode, in the same proc.: if(jail){ while(!reading) sched_yield(); } jail mode has been dropped, together with that use, so let's finish dropping this. Also, remove some other useless definitions I met.

Fix it a bit (after some cross checking with "man arch_prctl"). There were: *) typos FS/GS and back *) FS in place of FS_BASE (and the same for GS) *) the procedure used put_user on &addr, where addr was the parameter (i.e. changed its param with put_user, completely useless) rather than interpreting addr as a pointer, as requested in this case (see the man page).

2005-05-28[PATCH] sh: PREEMPT_ACTIVE fixPaul Mundt
Port Paulus's ppc64 fix to sh: When the generic IRQ stuff went in, it seems that HARDIRQ_BITS got bumped from 9 (for ppc64) up to 12. Consequently, the PREEMPT_ACTIVE bit is now within HARDIRQ_MASK, and I get in_interrupt() falsely returning true when PREEMPT_ACTIVE is set, and thus a BUG_ON tripping in arch/ppc64/mm/tlb.c.
