As an identical match is wanted in this case, strcmp can be used instead. The semantic match that lead to detecting this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression foo; constant char *abc; @@ *strncmp(foo, abc, sizeof(abc)) // </smpl> Signed-off-by:

This is the counterpart to cba76717 ("pktcdvd: remove broken dev_t export of class devices"). Device is not registered using dev_t, so it should not be destroyed using device_destroy which looks up the device by dev_t. This will fail and adding the device again will fail with the "duplicate name" error. This is fixed using device_unregister instead of device_destroy. Signed-off-by:

The probe function passes a pointer to a struct fb_info to platform_set_drvdata(), so don't interpret the return value of platform_get_drvdata() as a pointer to struct imxfb_info. The original imxfb_info *fbi backlight_power was NULL but in imxfb_suspend it was 4 resulting in an oops as imxfb_suspend calls imxfb_disable_controller(fbi) which in turn has if (fbi->backlight_power) fbi->backlight_power(0); Signed-off-by:

In cgroup_create(), if alloc_css_id() returns failure, the errno is not propagated to userspace, so mkdir will fail silently. To trigger this bug, we mount blkio (or memory subsystem), and create more then 65534 cgroups. (The number of cgroups is limited to 65535 if a subsystem has use_id == 1) # mount -t cgroup -o blkio xxx /mnt # for ((i = 0; i < 65534; i++)); do mkdir /mnt/$i; done # mkdir /mnt/65534 (should return ENOSPC) # Signed-off-by:

Otherwise vmalloc_to_page() will BUG(). This also makes the kmem read/write implementation aligned with mem(4): "References to nonexistent locations cause errors to be returned." Here we return -ENXIO (inspired by Hugh) if no bytes have been transfered to/from user space, otherwise return partial read/write results. Signed-off-by:

The cache alias problem will happen if the changes of user shared mapping is not flushed before copying, then user and kernel mapping may be mapped into two different cache line, it is impossible to guarantee the coherence after iov_iter_copy_from_user_atomic. So the right steps should be: flush_dcache_page(page); kmap_atomic(page); write to page; kunmap_atomic(page); flush_dcache_page(page); More precisely, we might create two new APIs flush_dcache_user_page and flush_dcache_kern_page to replace the two flush_dcache_page accordingly. Here is a snippet tested on omap2430 with VIPT cache, and I think it is not ARM-specific: int val = 0x11111111; fd = open("abc", O_RDWR); addr = mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_SHARED, fd, 0); *(addr+0) = 0x44444444; tmp = *(addr+0); *(addr+1) = 0x77777777; write(fd, &val, sizeof(int)); close(fd); The results are not always 0x11111111 0x77777777 at the beginning as expected. Sometimes we see 0x44444444 0x77777777.

Eric Paris located a bug in idr. With IDR_BITS of 6, it grows to three layers when id 4096 is first allocated. When that happens, idr wraps incorrectly and searches the idr array ignoring the high bits. The following test code from Eric demonstrates the bug nicely. #include <linux/idr.h> #include <linux/kernel.h> #include <linux/module.h> static DEFINE_IDR(test_idr); int init_module(void) { int ret, forty95, forty96; void *addr; /* add 2 entries both with 4095 as the start address */ again1: if (!idr_pre_get(&test_idr, GFP_KERNEL)) return -ENOMEM; ret = idr_get_new_above(&test_idr, (void *)4095, 4095, &forty95); if (ret) { if (ret == -EAGAIN) goto again1; return ret; } if (forty95 != 4095) printk(KERN_ERR "hmmm, forty95=%d\n", forty95); again2: if (!idr_pre_get(&test_idr, GFP_KERNEL)) return -ENOMEM; ret = idr_get_new_above(&test_idr, (void *)4096, 4095, &forty96); if (ret) { if (ret == -EAGAIN) goto again2; return ret; } if (forty96 != 4096) printk(KERN_ERR "hmmm, forty96=%d\n", forty96); /* try to find the 2 entries, noticing that 4096 broke */ addr = idr_find(&test_idr, forty95); if ((int)addr != forty95) printk(KERN_ERR "hmmm, after find forty95=%d addr=%d\n", forty95, (int)addr); addr = idr_find(&test_idr, forty96); if ((int)addr != forty96) printk(KERN_ERR "hmmm, after find forty96=%d addr=%d\n", forty96, (int)addr); /* really weird, the entry which should be at 4096 is actually at 0!! */ addr = idr_find(&test_idr, 0); if ((int)addr) printk(KERN_ERR "found an entry at id=0 for addr=%d\n", (int)addr); idr_remove(&test_idr, forty95); idr_remove(&test_idr, forty96); return 0; } void cleanup_module(void) { } MODULE_AUTHOR("Eric Paris <eparis@redhat.com>"); MODULE_DESCRIPTION("Simple idr test"); MODULE_LICENSE("GPL"); This happens because when sub_alloc() back tracks it doesn't always do it step-by-step while the over-the-limit detection assumes step-by-step backtracking. The logic in sub_alloc() looks like the following. restart: clear pa[top level + 1] for end cond detection l = top level while (true) { search for empty slot at this level if (not found) { push id to the next possible value l++ A: if (pa[l] is clear) failed, return asking caller to grow the tree if (going up 1 level gives more slots to search) continue the while loop above with the incremented l else C: goto restart } adjust id accordingly to the found slot if (l == 0) return found id; create lower level if not there yet record pa[l] and l-- } Test A is the fail exit condition but this assumes that failure is propagated upwared one level at a time but the B optimization path breaks the assumption and restarts the whole thing with a start value which is above the possible limit with the current layers. sub_alloc() assumes the start id value is inside the limit when called and test A is the only exit condition check, so it ends up searching for empty slot while ignoring high set bit. So, for 4095->4096 test, level0 search fails but pa[1] contains a valid pointer. However, going up 1 level wouldn't give any more empty slot so it takes C and when the whole thing restarts nobody notices the high bit set beyond the top level. This patch fixes the bug by changing the fail exit condition check to full id limit check.
