if the timezone file fails to load, due to late initialization of sp->goahead
to false in tzload, causing localsub to return NULL in the "cannot happen"
case. The fix is belt and suspenders:
- initialize sp->goback and sp->goahead very early in tzload
- replace all malloc calls with callocs, and remove the bogus
casts (it is not the 70's anymore!)
after readdir is called for the root dir the first time (yes,
there's still a window of wrong link count after the fs is mounted.
it's currently quite difficult to call sftp_readdir() from outside
the main loop).
Should fix "find /mnt" problem for a mountpoint with more than the
"guessed" amount of subdirectories, as reported by dyoung.
They will cause unnecessary non-equiv alias handling on PA1.x machines if
PA2.0 cpu support is compiled into the kernel. GENERIC currently doesn't
have this support enabled.
The performance hit of this needs testing.
- drop the notion of frags (LFS fragments) vs fsb (FFS fragments)
The code uses a complicated unity function that just makes the
code difficult to understand.
- support larger sector sizes. Fix disk address computations
to use DEV_BSIZE in the kernel as required by device drivers
and to use sector sizes in userland.
- Fix several locking bugs in lfs_bio.c and lfs_subr.c.
three registers. Let us think of the kernel operating the registers
in two steps:
1) Select: enable configuration cycles and select a range of
configuration-space addresses.
2) Access: read or write a word in PCI configuration space.
To make the steps more explicit, extract some helper subroutines
from pci_conf_read(9) and pci_conf_write(9):
pci_conf_selector(tag, reg): from a pcitag_t and a register offset,
create a word that enables configuration cycles and selects a
configuration address range.
pci_conf_select(w): for `w' a word created by pci_conf_selector(),
enable configuration cycles and select the address range indicated
by `w'.
pci_conf_select(0): disable configuration cycles.
pci_conf_port(tag, reg): map a pcitag_t and a register offset to an I/O
port where the configuration access should occur.
While I'm in here, change the panic(9) calls to panic("%s: ...",
__func__) instead of hard-coding a subroutine name.
- Apply the patch for 82575 from Wolfgang Stukenbrock (PR#42422). We use
only one RX ring and with the legacy mode.
- Add support for 82576.
- Partial support for 82580.
- Partial support for the serdes systems.
