Patch "m68k: add missing SOFTIRQENTRY_TEXT linker section" has been added to the 4.14-stable tree

This is a note to let you know that I've just added the patch titled m68k: add missing SOFTIRQENTRY_TEXT linker section to the 4.14-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=sum… The filename of the patch is: m68k-add-missing-softirqentry_text-linker-section.patch and it can be found in the queue-4.14 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable(a)vger.kernel.org> know about it. >From foo@baz Fri Feb 23 11:45:09 CET 2018 From: Greg Ungerer <gerg(a)linux-m68k.org> Date: Tue, 14 Nov 2017 11:50:07 +1000 Subject: m68k: add missing SOFTIRQENTRY_TEXT linker section From: Greg Ungerer <gerg(a)linux-m68k.org> [ Upstream commit 969de0988b77e5a57aac2f7270191a3c50540c52 ] Commit be7635e7287e ("arch, ftrace: for KASAN put hard/soft IRQ entries into separate sections") added a new linker section, SOFTIRQENTRY_TEXT, to the linker scripts for most architectures. It didn't add it to any of the linker scripts for the m68k architecture. This was not really a problem because it is only defined if either of CONFIG_FUNCTION_GRAPH_TRACER or CONFIG_KASAN are enabled - which can never be true for m68k. However commit 229a71860547 ("irq: Make the irqentry text section unconditional") means that SOFTIRQENTRY_TEXT is now always defined. So on m68k we now end up with a separate ELF section for .softirqentry.text instead of it being part of the .text section. On some m68k targets in some configurations this can also cause a fatal link error: LD vmlinux /usr/local/bin/../m68k-uclinux/bin/ld.real: section .softirqentry.text loaded at [0000000010de10c0,0000000010de12dd] overlaps section .rodata loaded at [0000000010de10c0,0000000010e0fd67] To fix add in the missing SOFTIRQENTRY_TEXT section into the m68k linker scripts. I noticed that m68k is also missing the IRQENTRY_TEXT section, so this patch also adds an entry for that too.

If multiple SD work requests are posted simultaneously, the sdbuf is reused by all WQEs and new WQEs can corrupt previous WQEs sdbuf leading to incorrect SD programming. Fix this by allocating one sdbuf per CQP SQ WQE. When an SD command is posted, it will use the corresponding sdbuf for the WQE.

However, this buffer is a flexible array, allocated together with the structure during .probe(). As the buffer is no longer the last member, writing to it corrupts the newly added member after it. During device removal, the corrupted member will be used as a pointer, leading to a crash. This went unnoticed, as the flexible array was declared as "buffer[0]" instead of "buffer[]", and thus did not trigger a "flexible array member not at end of struct" error from gcc. Move the gpiod_oe field up to fix this, and drop the zero from the array size to prevent future similar bugs.

From: Zumeng Chen <zumeng.chen(a)gmail.com> [ Upstream commit 58117672943734715bbe7565ac9f062effa524f0 ] According to LS1021A RM, the value of PAL can be set so that the start of the IP header in the receive data buffer is aligned to a 32-bit boundary. Normally, setting PAL = 2 provides minimal padding to ensure such alignment of the IP header. However every incoming packet's 8-byte time stamp will be inserted into the packet data buffer as padding alignment bytes when hardware time stamping is enabled.
