+Subject: ALSA: trident: Suppress gcc string warning
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Takashi Iwai <tiwai@suse.de>
+
+commit d6b340d7cb33c816ef4abe8143764ec5ab14a5cc upstream.
+
+The meddlesome gcc warns about the possible shortname string in
+trident driver code:
+ sound/pci/trident/trident.c: In function ‘snd_trident_probe’:
+ sound/pci/trident/trident.c:126:2: warning: ‘strcat’ accessing 17 or more bytes at offsets 36 and 20 may overlap 1 byte at offset 36 [-Wrestrict]
+ strcat(card->shortname, card->driver);
+
+It happens since gcc calculates the possible string size from
+card->driver, but this can't be true since we did set the string just
+before that, and they are much shorter.
+
+For shutting it up, use the exactly same string set to card->driver
+for strcat() to card->shortname, too.

+
+From: Sam Bobroff <sbobroff@linux.ibm.com>
+
+commit dc25ab067645eabd037f1a23d49a666f9e0b8c68 upstream.
+
+If the platform has no IO space, ioregs is placed next to the already
+allocated regs. In this case, it should not be separately freed.
+
+This prevents a kernel warning from __vunmap "Trying to vfree()
+nonexistent vm area" when unloading the driver.

+There's an error when compiled with restrict:

+Subject: scsi: csiostor: Avoid content leaks and casts
+
+From: Kees Cook <keescook@chromium.org>
+
+commit 42c335f7e67029d2e01711f2f2bc6252277c8993 upstream.
+
+When copying attributes, the len argument was padded out and the
+resulting memcpy() would copy beyond the end of the source buffer.
+Avoid this, and use size_t for val_len to avoid all the casts.
+Similarly, avoid source buffer casts and use void *.
+
+Additionally enforces val_len can be represented by u16 and that the DMA
+buffer was not overflowed. Fixes the size of mfa, which is not
+FC_FDMI_PORT_ATTR_MAXFRAMESIZE_LEN (but it will be padded up to 4). This
+was noticed by the future CONFIG_FORTIFY_SOURCE checks.

+
+commit 81df022b688d43d2a3667518b2f755d384397910 upstream.
+
+Cleanly fill memory for "vendor" and "model" with 0-bytes for the
+"compatible" case rather than adding only a single 0 byte. This
+simplifies the devinfo code a a bit, and avoids mistakes in other places
+of the code (not in current upstream, but we had one such mistake in the
+SUSE kernel).

+Subject: uprobes: Fix handle_swbp() vs. unregister() + register() race once more
+
+From: Andrea Parri <andrea.parri@amarulasolutions.com>
+
+commit 09d3f015d1e1b4fee7e9bbdcf54201d239393391 upstream.
+
+Commit:
+
+ 142b18ddc8143 ("uprobes: Fix handle_swbp() vs unregister() + register() race")
+
+added the UPROBE_COPY_INSN flag, and corresponding smp_wmb() and smp_rmb()
+memory barriers, to ensure that handle_swbp() uses fully-initialized
+uprobes only.
+
+However, the smp_rmb() is mis-placed: this barrier should be placed
+after handle_swbp() has tested for the flag, thus guaranteeing that
+(program-order) subsequent loads from the uprobe can see the initial
+stores performed by prepare_uprobe().
+
+Move the smp_rmb() accordingly. Also amend the comments associated
+to the two memory barriers to indicate their actual locations.
