2021-05-14xen/swiotlb: check if the swiotlb has already been initializedStefano Stabellini1-0/+5
xen_swiotlb_init calls swiotlb_late_init_with_tbl, which fails with -ENOMEM if the swiotlb has already been initialized. Add an explicit check io_tlb_default_mem != NULL at the beginning of xen_swiotlb_init. If the swiotlb is already initialized print a warning and return -EEXIST. On x86, the error propagates. On ARM, we don't actually need a special swiotlb buffer (yet), any buffer would do. So ignore the error and continue.

Mohammed reports (https://bugzilla.kernel.org/show_bug.cgi?id=213029) the commit e4ab4658f1cf ("clocksource/drivers/hyper-v: Handle vDSO differences inline") broke vDSO on x86. The problem appears to be that VDSO_CLOCKMODE_HVCLOCK is an enum value in 'enum vdso_clock_mode' and '#ifdef VDSO_CLOCKMODE_HVCLOCK' branch evaluates to false (it is not a define). Use a dedicated HAVE_VDSO_CLOCKMODE_HVCLOCK define instead.

Merge VT_RESIZEX fixes from Maciej Rozycki: "I got to the bottom of the issue with VT_RESIZEX recently discussed and came up with this small patch series, fixing an additional issue that I originally thought might be broken VGA hardware emulation with my laptop, which however turned out to be intertwined with the original problem and also a regression introduced somewhat later. The fix for that because the first patch, and then to make backporting feasible I had to put a revert of the offending change from last September next, followed by a proper fix for the framebuffer issue that change had tried to address. See individual change descriptions for details. These have been verified with true VGA hardware (a Trident TVGA8900 ISA video adapter) using various combinations of `svgatextmode' and `setfont' command invocations to change both the VT size and the font size, and also switching between the text console and X11, both by starting/stopping the X server and by switching between VTs. All this to ensure bringing the behaviour of VGA text console back to correct operation as it used to be with Linux 2.6.18" * emailed patches from Maciej W. Rozycki <macro@orcam.me.uk>: vt: Fix character height handling with VT_RESIZEX vt_ioctl: Revert VT_RESIZEX parameter handling removal vgacon: Record video mode changes with VT_RESIZEX
2021-05-13vt: Fix character height handling with VT_RESIZEXMaciej W. Rozycki2-25/+25
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.

Revert the removal of code handling extra VT_RESIZEX ioctl's parameters beyond those that VT_RESIZE supports, fixing a functional regression causing `svgatextmode' not to resize the VT anymore. As a consequence of the reverted change when the video adapter is 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), the VT geometry does not get updated and only upper two thirds of the screen are used for the VT, and the lower part remains blank. The proportions change according to text mode geometries chosen. Revert the change verbatim then, bringing back previous VT resizing. Signed-off-by: Maciej W.

2021-05-13vgacon: Record video mode changes with VT_RESIZEXMaciej W. Rozycki1-3/+11
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.

The issue is gone after setting "power_dpm_force_performance_level" to "high". Following the indication, we found that the issue occurs when sclk is too low. So resolve the issue by disabling sclk switching when there are two monitors requires high pixelclock (> 297MHz). v2: - Only apply the fix to Oland.

2021-05-13xhci: Fix giving back cancelled URBs even if halted endpoint can't resetMathias Nyman1-5/+11
Commit 9ebf30007858 ("xhci: Fix halted endpoint at stop endpoint command completion") in 5.12 changes how cancelled URBs are given back. To cancel a URB xhci driver needs to stop the endpoint first. To clear a halted endpoint xhci driver needs to reset the endpoint. In rare cases when an endpoint halt (error) races with a endpoint stop we need to clear the reset before removing, and giving back the cancelled URB. The above change in 5.12 takes care of this, but it also relies on the reset endpoint completion handler to give back the cancelled URBs. There are cases when driver refuses to queue reset endpoint commands, for example when a link suddenly goes to an inactive error state. In this case the cancelled URB is never given back. Fix this by giving back the URB in the stop endpoint if queuing a reset endpoint command fails.

2021-05-12ACPI: NFIT: Fix support for variable 'SPA' structure sizeDan Williams1-4/+11
ACPI 6.4 introduced the "SpaLocationCookie" to the NFIT "System Physical Address (SPA) Range Structure". The presence of that new field is indicated by the ACPI_NFIT_LOCATION_COOKIE_VALID flag. Pre-ACPI-6.4 firmware implementations omit the flag and maintain the original size of the structure. Update the implementation to check that flag to determine the size rather than the ACPI 6.4 compliant definition of 'struct acpi_nfit_system_address' from the Linux ACPICA definitions. Update the test infrastructure for the new expectations as well, i.e. continue to emulate the ACPI 6.3 definition of that structure. Without this fix the kernel fails to validate 'SPA' structures and this leads to a crash in nfit_get_smbios_id() since that routine assumes that SPAs are valid if it finds valid SMBIOS tables.

2021-05-12tpm: fix error return code in tpm2_get_cc_attrs_tbl()Zhen Lei1-0/+1
If the total number of commands queried through TPM2_CAP_COMMANDS is different from that queried through TPM2_CC_GET_CAPABILITY, it indicates an unknown error. In this case, an appropriate error code -EFAULT should be returned. However, we currently do not explicitly assign this error code to 'rc'. As a result, 0 was incorrectly returned.
