drawterm, factotum, secstore and the auth commands
all had ther own implementation of readcons. we
want to have one common function for this to avoid
the duplication, so putting that in libauthsrv.
introduce PASSWDLEN which makes the use more explicit
than ANAMELEN.
when we get eof, stop the loop immidiately and do not
rely on the read to eventually return an error.
when convM2S() fails to decode the message, error out
and stop the loop. there is no point in continuing.
given that the memory leaks have been fixed, theres no need
for the obscure restart feature which is not reliable anyway.
remove the code updating procname on each 9p request.
handle convM2S error by exiting the service loop, dont read
9p channel after eof.
we used to not sign extend if the destination was unsigned
uvlong, which is wrong. we have to sign extend only based
on the signedness of the source (it gets propagated to vlong)
this bug hit in hjfs in the newentry() function, causing file
creation to fail with "create -- phase error":
newentry(...)
{
uvlong sj;
int si;
...
sj = si = -1;
...
}
usually, the plan9 partition table is contained in
the first 9fat partition after the pbs/fat header,
but when no 9fat partition is requested, we have
to make sure partitions wont overlap the partition
table (start at sector offset >= 2).
the pause function is different from just accessing the menu: it pauses both
single and multiplayer games, stops music and sound, and is recorded in demos
(does not cause a desync, unlike menu access).
this uses Kprint rather than Kbreak because Kbreak is e.g. Kctl+pause on some
keyboards.
the first time rtl8169link is called (from rtl8169pnp), the link isn't up, so
setting edev->mbps based on Phystatus register is skipped. edev->mbps is then
still set at the default 100, and that ends up being what devether uses.
this is why some rtl8169 cards are misprinted as 100Mbps in kmesg.
later, after rtl8169link is called again from rtl8169interrupt, the link is up
and edev->mbps is set to the correct value (as shown by e.g. /net/ether0/stats).
so instead, set speed regardless of link status.
blazing doors are a "fast" door type with its own sound effects, introduced in
doom2. doom2 map 2 has one right at the beginning.
this fixes two bugs:
- when a closing blazing door is completely shut, the closing sound effect is
erroneously played again (the first time being when it began closing). this
gives the impression of two doors closing.
- when reopening a closing blazing door (standing underneath a blazing door
while it's closing), the sound effect for regular doors opening is played,
instead of the one for blazing doors, because of a missing case in the switch
statement.
data[mn] and link[mn] are 24-bit values.
in the expression 'm = (n * ((freq * bpp)/8)) / (lsclk * lanes)',
uvlongs are used to prevent integer overflow, but since freq, bpp, lsclk and
lanes are all ints, the cast to uvlong does not happen until it's too late,
getting a wrong value.
instead, use u32int for m and n, and use casts where necessary.
example of bad calculation:
freq = 141400000
lsclk = 270000000
lanes = 2
bpp = 18
→ 0x7f3ee1ca6 (correct value: 0x4b69d0)
when ndb/dns runs as a resolver only (cfg.cachedb == 0),
we still want to purge the "local#" db records to reread
dns server configuration or react to changed ip addresses.
removing old poolcheck and dncheck code, these bugs have
been fixed a long time ago.
the onscreen cursor shows the cursor of the current
focused window or the window it points at. if there
is no window, then we set the default cursor (nil).
the arm compiler can lift long->vlong casts on multiplcation
and convert 64x64->64 multiplication into a 32x32->64 one
with optional 64 bit accumulate.
