When the bridge recomputes features, it does not maintain the constraint that SG/GSO must be off if TX checksum is off. This patch adds that constraint. On a completely unrelated note, I've also added TSO6 and TSO_ECN feature bits if GSO is enabled on the underlying device through the new NETIF_F_GSO_SOFTWARE macro.

Fix a subtle race condition between bnx2_start_xmit() and bnx2_tx_int() similar to the one in tg3 discovered by Herbert Xu: CPU0 CPU1 bnx2_start_xmit() if (tx_ring_full) { tx_lock bnx2_tx() if (!netif_queue_stopped) netif_stop_queue() if (!tx_ring_full) update_tx_ring netif_wake_queue() tx_unlock } Even though tx_ring is updated before the if statement in bnx2_tx_int() in program order, it can be re-ordered by the CPU as shown above. This scenario can cause the tx queue to be stopped forever if bnx2_tx_int() has just freed up the entire tx_ring. The possibility of this happening should be very rare though. The following changes are made, very much identical to the tg3 fix: 1. Add memory barrier to fix the above race condition. 2. Eliminate the private tx_lock altogether and rely solely on netif_tx_lock. This eliminates one spinlock in bnx2_start_xmit() when the ring is full. 3. Because of 2, use netif_tx_lock in bnx2_tx_int() before calling netif_wake_queue(). 4. Add memory barrier to bnx2_tx_avail(). 5. Add bp->tx_wake_thresh which is set to half the tx ring size. 6. Check for the full wake queue condition before getting netif_tx_lock in tg3_tx(). This reduces the number of unnecessary spinlocks when the tx ring is full in a steady-state condition.

this minor patch fixes the description of net.ipv4.tcp_mem sysctl in ip-sysctl.txt - the headline names the values "min, pressure, max", while the description uses the "low, pressure, high" values. Both tcp_rmem and tcp_wmem descriptions use the "min, pressure, max" values, so I have changed the tcp_mem to match this and not vice versa.

- On archs that have no-exec support, we vmalloc() a executable scratch area of PAGE_SIZE and divide it up into an array of slots of maximum instruction size for that arch - On a kprobe registration, the original instruction is copied to the first available free slot, so if multiple kprobes are registered, chances are, they get contiguous slots - On POWER4, due to not having coherent icaches, we could hit a situation where a probe that is registered on one processor, is hit immediately on another. This second processor could have fetched the stream of text from the out-of-line single-stepping area *before* the probe registration completed, possibly due to an earlier (and a different) kprobe hit and hence would see stale data at the slot. Executing such an arbitrary instruction lead to a problem as reported in LTC bugzilla 23555. The correct solution is to call flush_icache_range() as soon as the instruction is copied for out-of-line single-stepping, so the correct instruction is seen on all processors. Thanks to Will Schmidt who tracked this down.

In the case of a system hang, the user will invoke soft-reset to initiate the kdump boot. If xmon is enabled, the CPU(s) enter into the xmon debugger. Unfortunately, the secondary CPU(s) will return to the hung state when they exit from the debugger (returned from die() -> system_reset_exception()). This causes a problem in kdump since the hung CPU(s) will not respond to the IPI sent from kdump. This patch fixes the issue by calling crash_kexec_secondary() directly from system_reset_exception() without returning to the previous state. These secondary CPUs wait 5ms until the kdump boot is started by the primary CPU. In the case we exited from the debugger to "recover" (command 'x' in xmon) the primary and the secondary CPUs will all return from die() -> system_reset_exception() ->crash_kexec_secondary() wait 5ms, then return to the previous state. A kdump boot is not started in this case. Signed-off-by: NHaren Myneni <haren@us.ibm.com> Signed-off-by: NDavid Wilder <dwilder@us.ibm.com> Signed-off-by: NPaul Mackerras <paulus@samba.org>

There is a small but annoying bug in scripts/mod/file2alias.c which causes it to generate invalid aliases for input devices on 64 bit archs. This causes joydev.ko to not be automaticly loaded when inserting a joystick, resulting in a non working joystick (for the average user). In scripts/mod/file2alias.c is the following code for generating the input aliases: static void do_input(char *alias, kernel_ulong_t *arr, unsigned int min, unsigned int max) { unsigned int i; for (i = min; i < max; i++) if (arr[i / BITS_PER_LONG] & (1 << (i%BITS_PER_LONG))) sprintf(alias + strlen(alias), "%X,*", i); } On 32 bits systems, this correctly generates "0,*" for the first alias, "8,*" for the second etc. However on 64 bits it generates: "0,*20,*" resp "8,*28,*" Notice how it adds 20 + first entry (hex) ! to the list of hex codes, which is 32 more then the first entry, thus is because the bit test above wraps at 32 bits instead of 64. scripts/mod/file2alias.c, line 379 reads: if (arr[i / BITS_PER_LONG] & (1 << (i%BITS_PER_LONG))) That should be: if (arr[i / BITS_PER_LONG] & (1L << (i%BITS_PER_LONG))) Notice the added 'L' after the 1, otherwise that is an 32 bit int instead of a 64 bit long, and when that int gets shifted >= 32 times, appearantly the number by which to shift is wrapped at 5 bits ( % 32) causing it to test a bit 32 bits too low.
