2020-09-02Add #define SID_SCSI2_RESPONSE 0x2 to allow elimination of another bunch ofKenneth R Westerback
magic numbers. As the nearby comment says '< 2 is obsolete. >2 is reserved'. So 0x2 is just right.

2020-08-30pppac(4) uses per cpu counters for collect `ifnet' statistics, but inmvs
pipex(4) layer this `ifnet' still uses `if_data'. Also pppx(4) doesn't use per cpu counters but `if_data'. Add per cpu counters to pppx(4) and pipex(4). This finishes interface statistics collecting mess. ok yasuoka@

handle the priority levels better and guarantee ordering of restoring the priority level after running an interrupt handler and checking for a new interrupt.
2020-08-30Lock all kernel PTE entries into the page tables, even "managed" onesMark Kettenis
entered by pmap_enter(9). Otherwise kernel stack pages get evicted and that doesn't end well. We probably only need to lock in wired pages and I will probably revisit this at some later stage. tested by deraadt@

2020-08-30PLL1(CPU_PLL) stability improvement for Allwinner H3/H2+SASANO Takayoshi
Due to unstable of PLL1, sometimes the system has hanged up especially at boot. This is observed at Allwinner H3/H2+ processor. To solve the problem, PLL1 setting procedure is same as Linux. 1. change clock source to 24MHz 2. wait 1usec (new) 3. disable PLL1 (new) 4. set new NKMP value, but M should be 1 5. re-enable PLL1 (new) 6. wait PLL1 stable (modified) 7. change clock source to PLL1 8. wait 1usec (new) Once disable PLL1 before setting NKMP is very important. And, sometimes LOCK flag is set even if PLL has not locked yet so wait for PLL is modified with simple delay() by the value of PLL_STABLE_TIME_REG1 register. Not only Allwinner H3/H2+ but also all (i.e. A64) Allwinner processors datasheet has "If the clock source is changed, at most to wait for 8 present running clock cycles." sentence at CPU clock source selection field of CPU/AXI configuration register. But this is ambiguous that _who_ should do _what_ during that cycles. It is unclear that changing clock source itself invoke PLL1 unstability. For safety, added 1usec wait after changing clock source like Linux. ok by kettenis@, thanks to adr at sdf dot org
2020-08-29More recent MMC specificiations add READ(12)/WRITE(12). So add cd_cmd_rw12()Kenneth R Westerback
and let cdstart() use it if the requested i/o is unable to fit into a READ(10). Certainly better than silently truncating the i/o into a READ(10)/WRITE(10).

2020-08-29Before clearing the kcov descriptor associated with a thread make sureanton
no other thread is currently within a remote section. Otherwise, the remote subsystem could end up in a broken state where it doesn't reset the necessary bits upon leaving the remote section. Therefore introduce the kr_barrier() routine which waits until all ongoing remote sections have been left. Also, extend the scope of the mutex to also cover fields of struct kcov_dev. This is necessary to ensure correctness. Reported-by: syzbot+64122a5f01be1b1abb96@syzkaller.appspotmail.com
2020-08-29Prepare to extend the scope of the kcov remote mutex by renaming it toanton
something more generic. It will soon cover the whole kcov subsystem.
2020-08-29Have [cd|sd]_cmd_rw[6|10|12|16] return the length of the created command andKenneth R Westerback
have the caller assign it to xs->cmdlen. Pass in xs->cmd instead of xs. A slightly cleaner API that provides the potential of detecting and reacting to a failure to create the desired command.

xs fields to a more convenient location, shrinking upcoming diffs. Nuke some Captain Obvious comments.

favour of simply using the device's claimed SCSI level of support. Except of course for ATAPI/USB devices which often don't claim anything. Keep assuming they are at least SCSI-2. Use consistant tests in sdminphys/cdminphys/sdstart/cdstart.

2020-08-27Fix a potential panic during free(9) which can be caused by an USBMarcus Glocker
device which returns a spurious value for wTotalLength on a configuration descriptor request. Therefore don't relay on wTotalLength for free(9) but on the length variable which was used for the malloc(9) before.

2020-08-27Clear endpoint stall on open(2) of /dev/uhidX to synchronize toggle bitPatrick Wildt
as needed on xhci(4) machines. On non-xhci(4) we save and restore the toggle bit on close/open of a pipe. With xhci(4) this does not seem to be possible, at least I haven't yet found it. This means that on those machines with xhci(4), after a pipe close/open, the device will use the previous state, while xhci(4)'s state is reset to default. By issuing a clear endpoint stall we reset the device's toggle bit. Now every time a /dev/uhid is (re-)opened the state should be synchronized. Discussed with damien@, mpi@ and Pedro Marteletto ok markus@
2020-08-27Improve write un-protecting of kernel memory. For the Computrace modulePatrick Wildt
on the HP EliteBook 830 G6 we added a workaround which tries to re-map the pages where we want to place to kernel read-write. On some machines though this workaround causes a regression. Fix those by changing a few things: Only set the writeable bit if it isn't set yet. Un-protect write-protected page directories. Skip lower levels if large-page is set, since the next level is already a page. Don't do anything at all if paging is disabled. From Christian Ehrhardt ok bluhm@ tobhe@
