+Subject: atm: he: fix sign-extension overflow on large shift
+
+[ Upstream commit cb12d72b27a6f41325ae23a11033cf5fedfa1b97 ]
+
+Shifting the 1 by exp by an int can lead to sign-extension overlow when
+exp is 31 since 1 is an signed int and sign-extending this result to an
+unsigned long long will set the upper 32 bits. Fix this by shifting an
+unsigned long.
+
+Detected by cppcheck:
+(warning) Shifting signed 32-bit value by 31 bits is undefined behaviour

+Subject: isdn: avm: Fix string plus integer warning from Clang
+
+[ Upstream commit 7afa81c55fca0cad589722cb4bce698b4803b0e1 ]
+
+A recent commit in Clang expanded the -Wstring-plus-int warning, showing
+some odd behavior in this file.
+
+drivers/isdn/hardware/avm/b1.c:426:30: warning: adding 'int' to a string does not append to the string [-Wstring-plus-int]
+ cinfo->version[j] = "\0\0" + 1;
+ ~~~~~~~^~~
+drivers/isdn/hardware/avm/b1.c:426:30: note: use array indexing to silence this warning
+ cinfo->version[j] = "\0\0" + 1;
+ ^
+ & [ ]
+1 warning generated.
+
+This is equivalent to just "\0". Nick pointed out that it is smarter to
+use "" instead of "\0" because "" is used elsewhere in the kernel and
+can be deduplicated at the linking stage.

+
+[ Upstream commit 2ff33d6637393fe9348357285931811b76e1402f ]
+
+The functions isdn_tty_tiocmset() and isdn_tty_set_termios() may be
+concurrently executed.
+
+isdn_tty_tiocmset
+ isdn_tty_modem_hup
+ line 719: kfree(info->dtmf_state);
+ line 721: kfree(info->silence_state);
+ line 723: kfree(info->adpcms);

+ line 721: kfree(info->silence_state);
+ line 723: kfree(info->adpcms);
+ line 725: kfree(info->adpcmr);
+
+Thus, some concurrency double-free bugs may occur.
+
+These possible bugs are found by a static tool written by myself and
+my manual code review.
+
+To fix these possible bugs, the mutex lock "modem_info_mutex" used in
+isdn_tty_tiocmset() is added in isdn_tty_set_termios().

+
+[ Upstream commit 10628e3ecf544fa2e4e24f8e112d95c37884dc98 ]
+
+This function is supposed to return zero on success or negative error
+codes on error. Unfortunately, there is a bug so it sometimes returns
+non-zero, positive numbers on success.
+
+I noticed this bug during review and I can't test it. It does appear
+that the return is sometimes propogated back to _regmap_read() where all
+non-zero returns are treated as failure so this may affect run time.

+Subject: scsi: isci: initialize shost fully before calling scsi_add_host()
+
+[ Upstream commit cc29a1b0a3f2597ce887d339222fa85b9307706d ]
+
+scsi_mq_setup_tags(), which is called by scsi_add_host(), calculates the
+command size to allocate based on the prot_capabilities. In the isci
+driver, scsi_host_set_prot() is called after scsi_add_host() so the command
+size gets calculated to be smaller than it needs to be. Eventually,
+scsi_mq_init_request() locates the 'prot_sdb' after the command assuming it
+was sized correctly and a buffer overrun may occur.
+
+However, seeing blk_mq_alloc_rqs() rounds up to the nearest cache line
+size, the mistake can go unnoticed.
+
+The bug was noticed after the struct request size was reduced by commit
+9d037ad707ed ("block: remove req->timeout_list")
+
+Which likely reduced the allocated space for the request by an entire cache
+line, enough that the overflow could be hit and it caused a panic, on boot,
+at:
+
+ RIP: 0010:t10_pi_complete+0x77/0x1c0
+ Call Trace:
+ <IRQ>
+ sd_done+0xf5/0x340
+ scsi_finish_command+0xc3/0x120
+ blk_done_softirq+0x83/0xb0
+ __do_softirq+0xa1/0x2e6
+ irq_exit+0xbc/0xd0
+ call_function_single_interrupt+0xf/0x20
+ </IRQ>
+
+sd_done() would call scsi_prot_sg_count() which reads the number of
+entities in 'prot_sdb', but seeing 'prot_sdb' is located after the end of
+the allocated space it reads a garbage number and erroneously calls
+t10_pi_complete().
+
+To prevent this, the calls to scsi_host_set_prot() are moved into
+isci_host_alloc() before the call to scsi_add_host(). Out of caution, also
+move the similar call to scsi_host_set_guard().
+
+Fixes: 3d2d75254915 ("[SCSI] isci: T10 DIF support")
