'setup_find_cpu_node()' take a reference on the node it returns. This reference must be decremented when not needed anymore, or there will be a leak.
Add the missing 'of_node_put(cpu)'.
Note that 'setup_cpuinfo()' that also calls this function already has a correct 'of_node_put(cpu)' at its end.

[ Upstream commit dbb5afad100a828c97e012c6106566d99f041db6 ]
Suppose we have 2 threads, the group-leader L and a sub-theread T, both parked in ptrace_stop(). Debugger tries to resume both threads and does
ptrace(PTRACE_CONT, T); ptrace(PTRACE_CONT, L);
If the sub-thread T execs in between, the 2nd PTRACE_CONT doesn not resume the old leader L, it resumes the post-exec thread T which was actually now stopped in PTHREAD_EVENT_EXEC. In this case the PTHREAD_EVENT_EXEC event is lost, and the tracer can't know that the tracee changed its pid.
This patch makes ptrace() fail in this case until debugger does wait() and consumes PTHREAD_EVENT_EXEC which reports old_pid. This affects all ptrace requests except the "asynchronous" PTRACE_INTERRUPT/KILL.
The patch doesn't add the new PTRACE_ option to not complicate the API, and I _hope_ this won't cause any noticeable regression:
- If debugger uses PTRACE_O_TRACEEXEC and the thread did an exec and the tracer does a ptrace request without having consumed the exec event, it's 100% sure that the thread the ptracer thinks it is targeting does not exist anymore, or isn't the same as the one it thinks it is targeting.
- To some degree this patch adds nothing new. In the scenario above ptrace(L) can fail with -ESRCH if it is called after the execing sub-thread wakes the leader up and before it "steals" the leader's pid.
Test-case:
#include <stdio.h> #include <unistd.h> #include <signal.h> #include <sys/ptrace.h> #include <sys/wait.h> #include <errno.h> #include <pthread.h> #include <assert.h>
void *tf(void *arg) { execve("/usr/bin/true", NULL, NULL); assert(0);
return NULL; }
int main(void) { int leader = fork(); if (!leader) { kill(getpid(), SIGSTOP);
pthread_t th; pthread_create(&th, NULL, tf, NULL); for (;;) pause();
return 0; }
waitpid(leader, NULL, WSTOPPED);
ptrace(PTRACE_SEIZE, leader, 0, PTRACE_O_TRACECLONE | PTRACE_O_TRACEEXEC); waitpid(leader, NULL, 0);

int status, thread = waitpid(-1, &status, 0); assert(thread > 0 && thread != leader); assert(status == 0x80137f);

Why ???? * * Why WEXITED? because we have another kernel problem connected * to mt-exec. */ siginfo_t info; assert(waitid(P_PID, leader, &info, WSTOPPED|WEXITED|WNOWAIT) == 0); assert(info.si_pid == leader && info.si_status == 0x0405);

commit d201d7631ca170b038e7f8921120d05eec70d7c5 upstream.
When using smb2_copychunk_range() for large ranges we will run through several iterations of a loop calling SMB2_ioctl() but never actually free the returned buffer except for the final iteration. This leads to memory leaks everytime a large copychunk is requested.

commit 05ca447630334c323c9e2b788b61133ab75d60d3 upstream.
The initialization of MIDI devices that are found on some LINE6 drivers are currently done in a racy way; namely, the MIDI buffer instance is allocated and initialized in each private_init callback while the communication with the interface is already started via line6_init_cap_control() call before that point. This may lead to Oops in line6_data_received() when a spurious event is received, as reported by syzkaller.
This patch moves the MIDI initialization to line6_init_cap_control() as well instead of the too-lately-called private_init for avoiding the race. Also this reduces slightly more lines, so it's a win-win change.

commit 0edabdfe89581669609eaac5f6a8d0ae6fe95e7f upstream.
Mackie d.2 has an extension card for IEEE 1394 communication, which uses BridgeCo DM1000 ASIC. On the other hand, Mackie d.4 Pro has built-in function for IEEE 1394 communication by Oxford Semiconductor OXFW971, according to schematic diagram available in Mackie website. Although I misunderstood that Mackie d.2 Pro would be also a model with OXFW971, it's wrong. Mackie d.2 Pro is a model which includes the extension card as factory settings.
This commit fixes entries in Kconfig and comment in ALSA OXFW driver.

commit 8822702f6e4c8917c83ba79e0ebf2c8c218910d4 upstream.
Ubuntu users reported an audio bug on the Lenovo Yoga Slim 7 14IIL05, he installed dual OS (Windows + Linux), if he booted to the Linux from Windows, the Speaker can't work well, it has crackling noise, if he poweroff the machine first after Windows, the Speaker worked well.
Before rebooting or shutdown from Windows, the Windows changes the codec eapd coeff value, but the BIOS doesn't re-initialize its value, when booting into the Linux from Windows, the eapd coeff value is not correct. To fix it, set the codec default value to that coeff register in the alsa driver.

commit c81d3d24602540f65256f98831d0a25599ea6b87 upstream.
When multiple PCI devices get assigned to a guest right at boot, libxl incrementally populates the backend tree. The writes for the first of the devices trigger the backend watch. In turn xen_pcibk_setup_backend() will set the XenBus state to Initialised, at which point no further reconfigures would happen unless a device got hotplugged. Arrange for reconfigure to also get triggered from the backend watch handler.

commit 7ee06ddc4038f936b0d4459d37a7d4d844fb03db upstream.
If an origin target has no snapshots, o->split_boundary is set to 0. This causes BUG_ON(sectors <= 0) in block/bio.c:bio_split().
Fix this by initializing chunk_size, and in turn split_boundary, to rounddown_pow_of_two(UINT_MAX) -- the largest power of two that fits into "unsigned" type.

commit c699a0db2d62e3bbb7f0bf35c87edbc8d23e3062 upstream.
The following commands will crash the kernel:
modprobe brd rd_size=1048576 dmsetup create o --table "0 `blockdev --getsize /dev/ram0` snapshot-origin /dev/ram0" dmsetup create s --table "0 `blockdev --getsize /dev/ram0` snapshot /dev/ram0 /dev/ram1 N 0"
The reason is that when we test for zero chunk size, we jump to the label bad_read_metadata without setting the "r" variable. The function snapshot_ctr destroys all the structures and then exits with "r == 0". The kernel then crashes because it falsely believes that snapshot_ctr succeeded.
In order to fix the bug, we set the variable "r" to -EINVAL.

commit 99ae3417672a6d4a3bf68d4fc43d7c6ca074d477 upstream.
This reverts commit 9aa3aa15f4c2f74f47afd6c5db4b420fadf3f315.
Because of recent interactions with developers from @umn.edu, all commits from them have been recently re-reviewed to ensure if they were correct or not.
Upon review, it was determined that this commit is not needed at all so just revert it. Also, the call to lm80_init_client() was not properly handled, so if error handling is needed in the lm80_probe() function, then it should be done properly, not half-baked like the commit being reverted here did.

commit ed04fe8a0e87d7b5ea17d47f4ac9ec962b24814a upstream.
This reverts commit 1d84353d205a953e2381044953b7fa31c8c9702d.
Because of recent interactions with developers from @umn.edu, all commits from them have been recently re-reviewed to ensure if they were correct or not.
Upon review, this commit was found to be incorrect for the reasons below, so it must be reverted. It will be fixed up "correctly" in a later kernel change.
The original commit here, while technically correct, did not fully handle all of the reported issues that the commit stated it was fixing, so revert it until it can be "fixed" fully.
Note, ioremap() probably will never fail for old hardware like this, and if anyone actually used this hardware (a PowerMac era PCI display card), they would not be using fbdev anymore.

The original commit log for this change was incorrect, no "error handling code" was added, things will blow up just as badly as before if any of these cases ever were true. As this BUG_ON() never fired, and most of these checks are "obviously" never going to be true, let's just revert to the original code for now until this gets unwound to be done correctly in the future.

commit d03d1021da6fe7f46efe9f2a7335564e7c9db5ab upstream.
The fields, "toc" and "cd_info", of "struct gdrom_unit gd" are allocated in "probe_gdrom()". Prevent a memory leak by making sure "gd.cd_info" is deallocated in the "remove_gdrom()" function.
Also prevent double free of the field "gd.toc" by moving it from the module's exit function to "remove_gdrom()". This is because, in "probe_gdrom()", the function makes sure to deallocate "gd.toc" in case of any errors, so the exit function invoked later would again free "gd.toc".
The patch also maintains consistency by deallocating the above mentioned fields in "remove_gdrom()" along with another memory allocated field "gd.disk".

commit 9183f01b5e6e32eb3f17b5f3f8d5ad5ac9786c49 upstream.
As Peter points out, if we were to disconnect and then reconnect this driver from a device, the "global" state of the device would contain odd values and could cause problems. Fix this up by just initializing the whole thing to 0 at probe() time.
Ideally this would be a per-device variable, but given the age and the total lack of users of it, that would require a lot of s/./->/g changes for really no good reason.

This commit is not correct, it should not have used unlikely() and is not propagating the error properly to the calling function, so it should be reverted at this point in time. Also, if the check failed, the work queue was still assumed to be allocated, so further accesses would have continued to fail, meaning this patch does nothing to solve the root issues at all.

The change here was incorrect. While it is nice to check if niu_pci_eeprom_read() succeeded or not when using the data, any error that might have happened was not propagated upwards properly, causing the kernel to assume that these reads were successful, which results in invalid data in the buffer that was to contain the successfully read data.

commit e6e337708c22f80824b82d4af645f20715730ad0 upstream.
niu_pci_eeprom_read() may fail, so add checks to its return value and propagate the error up the callstack.
An examination of the callstack up to niu_pci_eeprom_read shows that:
niu_pci_eeprom_read() // returns int niu_pci_vpd_scan_props() // returns int niu_pci_vpd_fetch() // returns *void* niu_get_invariants() // returns int
since niu_pci_vpd_fetch() returns void which breaks the bubbling up, change its return type to int so that error is propagated upwards.

commit 6647f7a06eb030a2384ec71f0bb2e78854afabfe upstream.
Check return value of lp5xx_read and if non-zero, jump to code at end of the function, causing lp5523_stop_all_engines to be executed before returning the error value up the call chain. This fixes the original commit (248b57015f35) which was reverted due to the University of Minnesota problems.

commit 84460f01cba382553199bc1361f69a872d5abed4 upstream.
The function qlcnic_dl_lb_test() currently calls netdev_alloc_skb() without checking afterwards that the allocation succeeded. Fix this by checking if the skb is NULL and returning an error in such a case. Breaking out of the loop if the skb is NULL is not correct as no error would be reported to the caller and no message would be printed for the user.

The return of ioremap if not checked, and can lead to a NULL to be assigned to hga_vram. Potentially leading to a NULL pointer dereference.
The fix adds code to deal with this case in the error label and changes how the hgafb_probe handles the return of hga_card_detect.

commit d4d0ad57b3865795c4cde2fb5094c594c2e8f469 upstream.
Fix an issue with VGA console font size changes made after the initial video text mode has been changed with a user tool like `svgatextmode' calling the VT_RESIZEX ioctl. As it stands in that case the original screen geometry continues being used to validate further VT resizing.
Consequently when the video adapter is firstly reprogrammed from the original say 80x25 text mode using a 9x16 character cell (720x400 pixel resolution) to say 80x37 text mode and the same character cell (720x592 pixel resolution), and secondly the CRTC character cell updated to 9x8 (by loading a suitable font with the KD_FONT_OP_SET request of the KDFONTOP ioctl), the VT geometry does not get further updated from 80x37 and only upper half of the screen is used for the VT, with the lower half showing rubbish corresponding to whatever happens to be there in the video memory that maps to that part of the screen. Of course the proportions change according to text mode geometries and font sizes chosen.
Address the problem then, by updating the text mode geometry defaults rather than checking against them whenever the VT is resized via a user ioctl.

commit 860dafa902595fb5f1d23bbcce1215188c3341e6 upstream.
Restore the original intent of the VT_RESIZEX ioctl's `v_clin' parameter which is the number of pixel rows per character (cell) rather than the height of the font used.
For framebuffer devices the two values are always the same, because the former is inferred from the latter one. For VGA used as a true text mode device these two parameters are independent from each other: the number of pixel rows per character is set in the CRT controller, while font height is in fact hardwired to 32 pixel rows and fonts of heights below that value are handled by padding their data with blanks when loaded to hardware for use by the character generator. One can change the setting in the CRT controller and it will update the screen contents accordingly regardless of the font loaded.
The `v_clin' parameter is used by the `vgacon' driver to set the height of the character cell and then the cursor position within. Make the parameter explicit then, by defining a new `vc_cell_height' struct member of `vc_data', set it instead of `vc_font.height' from `v_clin' in the VT_RESIZEX ioctl, and then use it throughout the `vgacon' driver except where actual font data is accessed which as noted above is independent from the CRTC setting.
This way the framebuffer console driver is free to ignore the `v_clin' parameter as irrelevant, as it always should have, avoiding any issues attempts to give the parameter a meaning there could have caused, such as one that has led to commit 988d0763361b ("vt_ioctl: make VT_RESIZEX behave like VT_RESIZE"):
"syzbot is reporting UAF/OOB read at bit_putcs()/soft_cursor() [1][2], for vt_resizex() from ioctl(VT_RESIZEX) allows setting font height larger than actual font height calculated by con_font_set() from ioctl(PIO_FONT). Since fbcon_set_font() from con_font_set() allocates minimal amount of memory based on actual font height calculated by con_font_set(), use of vt_resizex() can cause UAF/OOB read for font data."
The problem first appeared around Linux 2.5.66 which predates our repo history, but the origin could be identified with the old MIPS/Linux repo also at: git://git.kernel.org/pub/scm/linux/kernel/git/ralf/linux.git as commit 9736a3546de7 ("Merge with Linux 2.5.66."), where VT_RESIZEX code in `vt_ioctl' was updated as follows:
if (clin) - video_font_height = clin; + vc->vc_font.height = clin;
making the parameter apply to framebuffer devices as well, perhaps due to the use of "font" in the name of the original `video_font_height' variable. Use "cell" in the new struct member then to avoid ambiguity.
