This patch makes it so that if a user provides a groupname/username
instead of an id, chown will automatically convert it to a gid/uid
using getgrnam() or getpwnam() respectively.
At the moment, the actual flags are ignored, but we correctly propagate them all
the way from the original mount() syscall to each custody that resides on the
mounted FS.
Before this, su would leave the process's extra GIDs untouched,
simply inheriting them from whoever spawned su.
Now we grab the target user's groups from /etc/group and setgroups().
Add missing keymap entries for the dollar sign and escape key and reformat
the Hungarian keymap.
Remove the workaround for "0x08", replace it with '\b'.
Fix the octal/hex mixup in the value of escape key. (033 != 0x33, 033 == 0x1B)
We now validate the full range of userspace memory passed into syscalls
instead of just checking that the first and last byte of the memory are
in process-owned regions.
This fixes an issue where it was possible to avoid rejection of invalid
addresses that sat between two valid ones, simply by passing a valid
address and a size large enough to put the end of the range at another
valid address.
I added a little test utility that tries to provoke EFAULT in various
ways to help verify this. I'm sure we can think of more ways to test
this but it's at least a start. :^)
Thanks to mozjag for pointing out that this code was still lacking!
Incidentally this also makes backtraces work again.
Fixes#989.
The new PCI subsystem is initialized during runtime.
PCI::Initializer is supposed to be called during early boot, to
perform a few tests, and initialize the proper configuration space
access mechanism. Kernel boot parameters can be specified by a user to
determine what tests will occur, to aid debugging on problematic
machines.
After that, PCI::Initializer should be dismissed.
PCI::IOAccess is a class that is derived from PCI::Access
class and implements PCI configuration space access mechanism via x86
IO ports.
PCI::MMIOAccess is a class that is derived from PCI::Access
and implements PCI configurtaion space access mechanism via memory
access.
The new PCI subsystem also supports determination of IO/MMIO space
needed by a device by checking a given BAR.
In addition, Every device or component that use the PCI subsystem has
changed to match the last changes.
