When timeout_clk is calculated the host->clock could be zero. So, instead of host->clock the calculation now uses mmc->f_max. Signed-off-by: NAndy Shevchenko <andriy.shevchenko@linux.intel.com> Cc: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: NChris Ball <cjb@laptop.org>

Sometimes host->clock could be zero which is a legal situation. This patch checks host->clock before usage as a denominator when timeout is calculated. A similar patch is applied for mmc core (see commit e9b86841, "mmc: fix division by zero in MMC core"). Without this patch, the execution of the sdhci_calc_timeout could end up with a backtrace: <0>[ 4.014319] divide error: 0000 [#1] PREEMPT SMP <4>[ 4.014352] Modules linked in: g_ether <4>[ 4.014376] <4>[ 4.014393] Pid: 33, comm: kworker/u:2 Not tainted 3.0.0+ #646 <4>[ 4.014421] EIP: 0060:[<c12fa38e>] EFLAGS: 00010046 CPU: 1 <4>[ 4.014449] EIP is at sdhci_calc_timeout+0x2e/0x100 <4>[ 4.014468] EAX: 00000000 EBX: f5930fc8 ECX: 00000000 EDX: 00000000 <4>[ 4.014488] ESI: f5291de8 EDI: f5291db8 EBP: f5291c6c ESP: f5291c50 <4>[ 4.014508] DS: 007b ES: 007b FS: 00d8 GS: 0000 SS: 0068 <0>[ 4.014529] Process kworker/u:2 (pid: 33, ti=f5290000 task=f53065a0 task.ti=f5290000) <0>[ 4.014546] Stack: <4>[ 4.014557] 00000082 c1054fdd f5291c78 04000000 f5930fc8 f5291de8 f5291db8 f5291cac <4>[ 4.014611] c12fab7c c107a98b f5291c88 c13b6d3f f593109c f5882000 f5291cac c1054fdd <4>[ 4.014663] 00000000 00000000 f5882000 00000082 f5930fc8 f5291db8 0000000a f5291ccc <0>[ 4.014716] Call Trace: <4>[ 4.014743] [<c1054fdd>] ? mod_timer+0x11d/0x380 <4>[ 4.014770] [<c12fab7c>] sdhci_prepare_data+0x2c/0x3a0 <4>[ 4.014798] [<c107a98b>] ? trace_hardirqs_off+0xb/0x10 <4>[ 4.014827] [<c13b6d3f>] ? _raw_spin_unlock_irqrestore+0x2f/0x60 <4>[ 4.014854] [<c1054fdd>] ? mod_timer+0x11d/0x380 <4>[ 4.014880] [<c12fc7db>] sdhci_send_command+0xdb/0x210 <4>[ 4.014906] [<c12fd5f3>] sdhci_request+0xc3/0x150 <4>[ 4.014932] [<c12ec56a>] mmc_start_request+0xda/0x200 <4>[ 4.014960] [<c120d7c2>] ? __raw_spin_lock_init+0x32/0x60 <4>[ 4.014989] [<c1066a85>] ? __init_waitqueue_head+0x35/0x50 <4>[ 4.015015] [<c12ec70b>] mmc_wait_for_req+0x7b/0x90 <4>[ 4.015045] [<c12f0c67>] mmc_send_cxd_data+0xf7/0x130 <4>[ 4.015076] [<c12ecbc0>] ? mmc_erase+0x140/0x140 <4>[ 4.015102] [<c12f139d>] mmc_send_ext_csd+0x1d/0x20 <4>[ 4.015125] [<c12efef0>] mmc_get_ext_csd+0x70/0x140 <4>[ 4.015151] [<c12effe8>] mmc_compare_ext_csds+0x28/0x190 <4>[ 4.015176] [<c12f039f>] mmc_init_card+0x24f/0x650 <4>[ 4.015201] [<c13b6d5d>] ? _raw_spin_unlock_irqrestore+0x4d/0x60 <4>[ 4.015226] [<c107fd9c>] ? trace_hardirqs_on_caller+0x11c/0x160 <4>[ 4.015255] [<c12f09a4>] mmc_attach_mmc+0xa4/0x190 <4>[ 4.015282] [<c12ee3f0>] mmc_rescan+0x210/0x240 <4>[ 4.015311] [<c105f9b6>] process_one_work+0x176/0x550 <4>[ 4.015336] [<c105f93a>] ? process_one_work+0xfa/0x550 <4>[ 4.015360] [<c12ee1e0>] ? mmc_init_erase+0x140/0x140 <4>[ 4.015385] [<c1061c2a>] worker_thread+0x12a/0x2c0 <4>[ 4.015410] [<c1061b00>] ? manage_workers.clone.18+0x100/0x100 <4>[ 4.015437] [<c1066244>] kthread+0x74/0x80 <4>[ 4.015463] [<c10661d0>] ? __init_kthread_worker+0x60/0x60 <4>[ 4.015490] [<c13b7dfa>] kernel_thread_helper+0x6/0xd <0>[ 4.015507] Code: 57 89 d7 56 53 89 c3 83 ec 10 8b 40 04 8b 72 28 f6 c4 10 89 45 f0 0f 85 91 00 00 00 85 f6 0f 84 c1 00 00 00 8b 4e 04 31 d2 89 c8 <f7> 73 58 ba d3 4d 62 10 89 c1 8b 06 f7 e2 c1 ea 06 01 d1 f7 45 <0>[ 4.015829] EIP: [<c12fa38e>] sdhci_calc_timeout+0x2e/0x100 SS:ESP 0068:f5291c50 Reported-by: NAlexander Shishkin <alexander.shishkin@linux.intel.com> Signed-off-by: NAndy Shevchenko <andriy.shevchenko@linux.intel.com> Signed-off-by: NChris Ball <cjb@laptop.org>

Computers have become a lot faster since we compromised on the partial MD4 hash which we use currently for performance reasons. MD5 is a much safer choice, and is inline with both RFC1948 and other ISS generators (OpenBSD, Solaris, etc.) Furthermore, only having 24-bits of the sequence number be truly unpredictable is a very serious limitation. So the periodic regeneration and 8-bit counter have been removed. We compute and use a full 32-bit sequence number. For ipv6, DCCP was found to use a 32-bit truncated initial sequence number (it needs 43-bits) and that is fixed here as well.

Two additional savage4 variants were added, but the S3_SAVAGE4_SERIES macro was incompletely modified, resulting in a false positive detection of a savage4 card regardless of which savage card is actually present. For non-savage4 series cards, such as a Savage/IX-MV card, this results in garbled video and/or a hard-hang at boot time. Fix this by changing an '||' to an '&&' in the S3_SAVAGE4_SERIES macro.

由 Kevin Hilman 提交于
Currently the use of pm_runtime_put_sync() is not safe from interrupts-disabled context because rpm_idle() will release the spinlock and enable interrupts for the idle callbacks. This enables interrupts during a time where interrupts were expected to be disabled, and can have strange side effects on drivers that expected interrupts to be disabled. This is not a bug since the documentation clearly states that only _put_sync_suspend() is safe in IRQ-safe mode. However, pm_runtime_put_sync() could be made safe when in IRQ-safe mode by releasing the spinlock but not re-enabling interrupts, which is what this patch aims to do. Problem was found when using some buggy drivers that set pm_runtime_irq_safe() and used _put_sync() in interrupts-disabled context.
