With addition of dummy clk_*() calls for non CONFIG_HAVE_CLK cases in clk.h, there is no need to have clk code enclosed in #ifdef CONFIG_HAVE_CLK, #endif macros. This also fixes error paths of probe(), as a goto is required in this patch. Signed-off-by: Viresh Kumar <viresh.kumar@st.com> Cc: Giuseppe Cavallaro <peppe.cavallaro@st.com> Acked-by: David S.

Many drivers are shared between architectures that may or may not have HAVE_CLK selected for them. To remove compilation errors for them we enclose clk_*() calls in these drivers within #ifdef CONFIG_HAVE_CLK, #endif. This patch removes the need of these CONFIG_HAVE_CLK statements, by introducing dummy routines when HAVE_CLK is not selected by platforms. So, definition of these routines will always be available. These calls will return error for platforms that don't select HAVE_CLK.

There's a small group of odd looking includes in smc37c669.c. These includes appear to be if zero-ed out ever since they were added to the tree (in v2.1.89). Their purpose is unclear to me. Perhaps they were used in someones build system. Whatever their purpose was, nothing else uses something comparable. This entire if zero-ed out block might as well be removed.

When the suid_dumpable sysctl is set to "2", and there is no core dump pipe defined in the core_pattern sysctl, a local user can cause core files to be written to root-writable directories, potentially with user-controlled content. This means an admin can unknowningly reintroduce a variation of CVE-2006-2451, allowing local users to gain root privileges. $ cat /proc/sys/fs/suid_dumpable 2 $ cat /proc/sys/kernel/core_pattern core $ ulimit -c unlimited $ cd / $ ls -l core ls: cannot access core: No such file or directory $ touch core touch: cannot touch `core': Permission denied $ OHAI="evil-string-here" ping localhost >/dev/null 2>&1 & $ pid=$! $ sleep 1 $ kill -SEGV $pid $ ls -l core -rw------- 1 root kees 458752 Jun 21 11:35 core $ sudo strings core | grep evil OHAI=evil-string-here While cron has been fixed to abort reading a file when there is any parse error, there are still other sensitive directories that will read any file present and skip unparsable lines. Instead of introducing a suid_dumpable=3 mode and breaking all users of mode 2, this only disables the unsafe portion of mode 2 (writing to disk via relative path). Most users of mode 2 (e.g. Chrome OS) already use a core dump pipe handler, so this change will not break them. For the situations where a pipe handler is not defined but mode 2 is still active, crash dumps will only be written to fully qualified paths. If a relative path is defined (e.g. the default "core" pattern), dump attempts will trigger a printk yelling about the lack of a fully qualified path.

efi_setup_pcdp_console() is called during boot to parse the HCDP/PCDP EFI system table and setup an early console for printk output. The routine uses ioremap/iounmap to setup access to the HCDP/PCDP table information. The call to ioremap is happening early in the boot process which leads to a panic on x86_64 systems: panic+0x01ca do_exit+0x043c oops_end+0x00a7 no_context+0x0119 __bad_area_nosemaphore+0x0138 bad_area_nosemaphore+0x000e do_page_fault+0x0321 page_fault+0x0020 reserve_memtype+0x02a1 __ioremap_caller+0x0123 ioremap_nocache+0x0012 efi_setup_pcdp_console+0x002b setup_arch+0x03a9 start_kernel+0x00d4 x86_64_start_reservations+0x012c x86_64_start_kernel+0x00fe This replaces the calls to ioremap/iounmap in efi_setup_pcdp_console() with calls to early_ioremap/early_iounmap which can be called during early boot. This patch was tested on an x86_64 prototype system which uses the HCDP/PCDP table for early console setup.

Commit a6bc32b8 ("mm: compaction: introduce sync-light migration for use by compaction") changed the declaration of migrate_pages() and migrate_huge_pages(). But it missed changing the argument of migrate_huge_pages() in soft_offline_huge_page(). In this case, we should call migrate_huge_pages() with MIGRATE_SYNC. Additionally, there is a mismatch between type the of argument and the function declaration for migrate_pages().

Jiri Kosina authored
Back in 2006, commit 1a2449a8 ("[I/OAT]: TCP recv offload to I/OAT") added support for receive offloading to IOAT dma engine if available. The code in tcp_rcv_established() tries to perform early DMA copy if applicable. It however does so without checking whether the userspace task is actually expecting the data in the buffer. This is not a problem under normal circumstances, but there is a corner case where this doesn't work -- and that's when MSG_TRUNC flag to recvmsg() is used. If the IOAT dma engine is not used, the code properly checks whether there is a valid ucopy.task and the socket is owned by userspace, but misses the check in the dmaengine case. This problem can be observed in real trivially -- for example 'tbench' is a good reproducer, as it makes a heavy use of MSG_TRUNC. On systems utilizing IOAT, you will soon find tbench waiting indefinitely in sk_wait_data(), as they have been already early-copied in tcp_rcv_established() using dma engine. This patch introduces the same check we are performing in the simple iovec copy case to the IOAT case as well. It fixes the indefinite recvmsg(MSG_TRUNC) hangs.

This reverts commit 5b3e7e6c. The problem that the original commit was attempting to fix can never happen in practice because validation is done one a per-flow basis rather than a per-packet basis.

When device flags are set using rtnetlink, IFF_PROMISC and IFF_ALLMULTI flags are handled specially. Function dev_change_flags sets IFF_PROMISC and IFF_ALLMULTI bits in dev->gflags according to the passed value but do_setlink passes a result of rtnl_dev_combine_flags which takes those bits from dev->flags. This can be easily trigerred by doing: tcpdump -i eth0 & ip l s up eth0 ip sets IFF_UP flag in ifi_flags and ifi_change, which is combined with IFF_PROMISC by rtnl_dev_combine_flags, causing __dev_change_flags to set IFF_PROMISC in gflags.

As Colin Cross ported my x86 change to ARM, he also pointed out that powerpc is also behind in this fix. The commit 722b3c74 "ftrace/graph: Trace function entry before updating index" fixes an issue with function graph tracing for x86, where if the called entry function decides not to trace interrupts, it can fail the check if an interrupt comes in just after the curr_ret_stack is updated. The solution is to call the entry function first, then update the curr_ret_stack if the entry function wants to be traced.
