Both 'i' and 'bits_per_entry' are signed integers but the result is a u64 block number. Cast i to u64 to avoid truncation on 32-bit targets. Found by Coverity (CID 200679). Signed-off-by:

The count variable is used to iterate down to (below) zero from the size of the bitmap and handle the one-filling the remainder of the last partial bitmap block. The loop conditional expects count to be signed in order to detect when the final block is processed, after which count goes negative. Unfortunately, a recent change made this unsigned along with some other related fields. The result of is this is that during mount, omfs_get_imap will overrun the bitmap array and corrupt memory unless number of blocks happens to be a multiple of 8 * blocksize. Fix by changing count back to signed: it is guaranteed to fit in an s32 without overflow due to an enforced limit on the number of blocks in the filesystem. Signed-off-by:

match_token() expects a NULL terminator at the end of the token list so that it would know where to stop. Not having one causes it to overrun to invalid memory. In practice, passing a mount option that omfs didn't recognize would sometimes panic the system. Signed-off-by:

sctp_v4_map_v6 was subtly writing and reading from members of a union in a way the clobbered data it needed to read before it read it. Zeroing the v6 flowinfo overwrites the v4 sin_addr with 0, meaning that every place that calls sctp_v4_map_v6 gets ::ffff:0.0.0.0 as the result. Reorder things to guarantee correct behaviour no matter what the union layout is. This impacts user space clients that open an IPv6 SCTP socket and receive IPv4 connections. Prior to 299ee user space would see a sockaddr with AF_INET and a correct address, after 299ee the sockaddr is AF_INET6, but the address is wrong.

For mq qdisc, we add per tx queue qdisc to root qdisc for display purpose, however, that happens too early, before the new dev->qdisc is finally set, this causes q->list points to an old root qdisc which is going to be freed right before assigning with a new one. Fix this by moving ->attach() after setting dev->qdisc.

Fix broken probe of da9052 regulators, which since commit b3f6c73d ("mfd: da9052-core: Fix platform-device id collision") use a non-deterministic platform-device id to retrieve static regulator information. Fortunately, adequate error handling was in place so probe would simply fail with an error message. Update the mfd-cell ids to be zero-based and use those to identify the cells when probing the regulator devices.

With recent debugging, I noticed that bpf_jit_disasm segfaults when there's no debugging output from the JIT compiler to the kernel log. Reason is that when regexec(3) doesn't match on anything, start/end offsets are not being filled out and contain some uninitialized garbage from stack. Thus, we need zero out offsets first.

Fix the bootpfile and bootpzfile make targets to creat BOOTP images. Both targets were broken due to some missing defines to re-map ELF constants. In addition the old code used the generic vsprintf function of the kernel which we now replace by a simple and much smaller implementation for the bootloader. Signed-off-by:

The 'arg' argument to copy_thread() is only ever used when forking a new kernel thread. Hence, rename it to 'kthread_arg' for clarity (and consistency with do_fork() and other arch-specific implementations of copy_thread()). Signed-off-by:

None of these files are actually using any __init type directives and hence don't need to include <linux/init.h>. Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next. Acked-by:

The srm console is always built in. It will never be modular, so using module_init as an alias for __initcall is rather misleading. Fix this up now, so that we can relocate module_init from init.h into module.h in the future. If we don't do this, we'd have to add module.h to obviously non-modular code, and that would be a worse thing. Direct use of __initcall is discouraged, vs prioritized ones. Use of device_initcall is consistent with what __initcall maps onto, and hence does not change the init order, making the impact of this change zero. Should someone with real hardware for boot testing want to change it later to arch_initcall or console_initcall, they can do that at a later date. Reviewed-by:

Commit 9a46ad6d "smp: make smp_call_function_many() use logic similar to smp_call_function_single()" has unified the way to handle single and multiple cross-CPU function calls. Now only one interrupt is needed for architecture specific code to support generic SMP function call interfaces, so kill the redundant single function call interrupt.

PCI core will initialize device MSI/MSI-X capability in pci_msi_init_pci_dev(). So device driver should use pci_dev->msi_cap/msix_cap to determine whether the device support MSI/MSI-X instead of using pci_find_capability(pci_dev, PCI_CAP_ID_MSI/MSIX). Access to PCIe device config space again will consume more time. Signed-off-by:

The newly added AEAD user-space isn't quite ready for prime time just yet. In particular it is conflicting with the AEAD single SG list interface change so this patch disables it now. Once the SG list stuff is completely done we can then renable this interface. Signed-off-by:
