Do netif_carrier_on() right after the IPv4 broadcast multicast group is joined, rather than waiting for all of the initial set of multicast group joins to finish. This allows at least IPv4 traffic to limp along on broken fabrics where not all multicast groups can be joined. Signed-off-by:

For 2.6.20 it mostly used to just not work, for 2.6.21-rc it crashes, this seems to be down to luck (bad or good). The libata-acpi code needs to avoid doing PCI work on non-PCI devices. This is one hack although it's not pretty and perhaps there is a "right" way to check if a struct device * is PCI ? Signed-off-by:

In my previous x86_64 thread fix, I forgot to initialize thread.arch.fs in arch_prctl. A process calling arch_prctl to set %fs would lose it on the next context switch. It also turns out that you can switch to a process which is in the process of exiting and which has lost its mm. In this case, it's worse than useless to try to call arch_prctl on the host process.

IA64 and ARM-OABI are currently using their own version of epoll compat_ code. An architecture needs epoll_event translation if alignof(u64) in 32 bit mode is different from alignof(u64) in 64 bit mode. If an architecture needs epoll_event translation, it must define struct compat_epoll_event in asm/compat.h and set CONFIG_HAVE_COMPAT_EPOLL_EVENT and use compat_sys_epoll_ctl and compat_sys_epoll_wait. All 64 bit architecture should use compat_sys_epoll_pwait. [sfr: restructure and move to fs/compat.c, remove MIPS version of compat_sys_epoll_pwait, use __put_user_unaligned] Signed-off-by:

[Bluetooth] Fix socket locking in hci_sock_dev_event() hci_sock_dev_event() uses bh_lock_sock() to lock the socket lock. This is not deadlock-safe against locking of the same socket lock in l2cap_connect_cfm() from softirq context. In addition to that, hci_sock_dev_event() doesn't seem to be called from softirq context, so it is safe to use lock_sock()/release_sock() instead. The lockdep warning can be triggered on my T42p simply by switching the Bluetooth off by the keyboard button. ================================= [ INFO: inconsistent lock state ] 2.6.21-rc2 #4 --------------------------------- inconsistent {in-softirq-W} -> {softirq-on-W} usage. khubd/156 [HC0[0]:SC0[0]:HE1:SE1] takes: (slock-AF_BLUETOOTH){-+..}, at: [<e0ca5520>] hci_sock_dev_event+0xa8/0xc5 [bluetooth] {in-softirq-W} state was registered at: [<c012d1db>] mark_lock+0x59/0x414 [<e0cef688>] l2cap_connect_cfm+0x4e/0x11f [l2cap] [<c012dfd7>] __lock_acquire+0x3e5/0xb99 [<e0cef688>] l2cap_connect_cfm+0x4e/0x11f [l2cap] [<c012e7f2>] lock_acquire+0x67/0x81 [<e0cef688>] l2cap_connect_cfm+0x4e/0x11f [l2cap] [<c036ee72>] _spin_lock+0x29/0x34 [<e0cef688>] l2cap_connect_cfm+0x4e/0x11f [l2cap] [<e0cef688>] l2cap_connect_cfm+0x4e/0x11f [l2cap] [<e0ca17c3>] hci_send_cmd+0x126/0x14f [bluetooth] [<e0ca4ce4>] hci_event_packet+0x729/0xebd [bluetooth] [<e0ca205b>] hci_rx_task+0x2a/0x20f [bluetooth] [<e0ca209d>] hci_rx_task+0x6c/0x20f [bluetooth] [<c012d7be>] trace_hardirqs_on+0x10d/0x14e [<c011ac85>] tasklet_action+0x3d/0x68 [<c011abba>] __do_softirq+0x41/0x92 [<c011ac32>] do_softirq+0x27/0x3d [<c0105134>] do_IRQ+0x7b/0x8f [<c0103dec>] common_interrupt+0x24/0x34 [<c0103df6>] common_interrupt+0x2e/0x34 [<c0248e65>] acpi_processor_idle+0x1b3/0x34a [<c0248e68>] acpi_processor_idle+0x1b6/0x34a [<c010232b>] cpu_idle+0x39/0x4e [<c04bab0c>] start_kernel+0x372/0x37a [<c04ba42b>] unknown_bootoption+0x0/0x202 [<ffffffff>] 0xffffffff Signed-off-by:Jiri Kosina <jkosina@suse.cz> Acked-by:

Also PTRACE_OLDSETOPTIONS should be accepted, as done by kernel/ptrace.c and forced by binary compatibility. UML/32bit breaks because of this - since it is wise enough to use PTRACE_OLDSETOPTIONS to be binary compatible with 2.4 host kernels. Until 2.6.17 (commit f0f2d653) we had: default: return sys_ptrace(request, pid, addr, data); Instead here we have: case PTRACE_GET_THREAD_AREA: case ...: return sys_ptrace(request, pid, addr, data); default: return -EINVAL; This change was a style change - when a case is added, it must be explicitly tested this way. In this case, not enough testing was done. Cc: Andi Kleen <ak@suse.de> Signed-off-by:

Since both UML consoles do not use percpu variables, they may be called when the cpu is still offline, and they may be marked CON_ANYTIME (this is documented in kernel/printk.c, grep for CON_ANYTIME to find mentions of this). Works well in testing done with lock debug enabled, should be safe but is not needed for next release. This would probably help also stderr_console.c, but this is yet to test. Signed-off-by:

Fastest fsys_getcpu: 28 itc counts. fsys_getcpu performance is largly impacted by whether data (node_to_cpu_map etc) is in cache. It can take fsys_getcpu up to ~150 itc counts in cold cache case.

Berhhard Walle noted that on his HP rx8640 he ended up with saved_max_pfn smaller than the highest address of system ram in /proc/iomem and proposed a patch to base the address on the unrounded and unfiltered EFI memory map address.

One change introduced by the workqueue removal patch is that adding an interface that is up to a bridge which is also up does not ever call br_stp_enable_port(), leaving the port in DISABLED state until we do ifconfig down and up or link events occur. The following patch to the br_add_if function fixes it. This is a regression introduced in 2.6.21. Submitted-by: Aji_Srinivas@emc.com Signed-off-by:

Inside pfkey_delete and xfrm_del_sa the audit hooks were not called if there was any permission/security failures in attempting to do the del operation (such as permission denied from security_xfrm_state_delete).

pfkey_spdget neither had an LSM security hook nor auditing for the removal of xfrm_policy structs. The security hook was added when it was moved into xfrm_policy_byid instead of the callers to that function by my earlier patch and this patch adds the auditing hooks as well. Signed-off-by:

Eric Paris authored
The security hooks to check permissions to remove an xfrm_policy were actually done after the policy was removed. Since the unlinking and deletion are done in xfrm_policy_by* functions this moves the hooks inside those 2 functions. There we have all the information needed to do the security check and it can be done before the deletion. Since auditing requires the result of that security check err has to be passed back and forth from the xfrm_policy_by* functions. This patch also fixes a bug where a deletion that failed the security check could cause improper accounting on the xfrm_policy (xfrm_get_policy didn't have a put on the exit path for the hold taken by xfrm_policy_by*) It also fixes the return code when no policy is found in xfrm_add_pol_expire. In old code (at least back in the 2.6.18 days) err wasn't used before the return when no policy is found and so the initialization would cause err to be ENOENT. But since err has since been used above when we don't get a policy back from the xfrm_policy_by* function we would always return 0 instead of the intended ENOENT. Also fixed some white space damage in the same area. Signed-off-by:

This reverts an earlier patch which disabled bidirectional mode, meaning that a listening (passive) socket was not allowed to write to the other (active) end of the connection. This mode had been disabled when there were problems with CCID3, but it imposes a constraint on socket programming and thus hinders deployment. A change is included to ignore RX feedback received by the TX CCID3 module. Many thanks to Andre Noll for pointing out this issue. Signed-off-by:
