Clear the any endpoint stall in the interrupt handler. All other
drivers do this and I am pretty sure we need to as well, though I have
yet to see a stall in the handler.
Add support for the Zoom 3095 USB Fax Modem. There are some problems
with this modem:
1) The CS descriptors were placed after all other descriptors rather
than in the Control Interface. This is true in both configurations
and is the issue this patch deals with.
2) Modem audio is not done on the modem. There is a second
configuration with an extra interface (3 interfaces) which presumably
is for handling audio. This patch does not support that.
3) The interrupts are raised a bit slowly. This means that pppd(8)
needs to wait a bit before trying to read from the link (i.e., just
before the get_input() loop in src/dist/pppd/pppd/main.c line 547).
If you don't wait, then DCD will not be detected high before that
first read and get_input() will drop the line. This is not a problem
if you use the "local" option to pppd(8) and ignore DCD, but that is
less than desirable.
4) You apparently have to toggle "RSDL (DCD) option"[1] when you
initialize the modem or you will never see a second DCD high interrupt
when redialing after a disconnect. Without this the pppd(8) "persist"
mode will not work. Presumably, some extra initialization is missing
from the driver for this chipset.
[1] Send the AT commands: AT&C0 followed by AT&C1 - doing it in one
command doesn't work. The AT commands for this modem are at:

variables: only free memory if the current value points to the same
memory area as the allocated block. This will prevent crashes if an
application changes the order of the environment array.
Unfortunately this is still not enough to stop zsh 4.2.* from crashing.
zsh 4.3.* works fine before and after this change.
section and allow this type to be overridden.
The ELF specification says it should always be uint32_t (Elf_Word), but
alpha decided to be different (not sure why). Define Elf_Symindx to be
uint64_t on alpha.
Alpha no longer uses non-standard definitions of Elf64_Sword and
Elf64_Word. Remove the ability to override these types.
Fixes ld.elf_so after Herculean effort from me and martin.
- Restore open on our own in fsycn and readdir, as the node may not already
be open, and FUSE really wants it to be. No need to close immediatly, it
can be done at inactive time.
= Write operations =
- fix a nasty bug that corrupted files on write (written added twice)
- Keep track of file size in order to honour PUFFS_IO_APPEND
= many fixes in rename =
- handler overwritten nodes correctly
- wait for all operations on the node to drain before doing rename, as
filesystems may not cope with operations on a moving file.
- setback PUFFS_SETBACK_INACT_N1 cannot be used from rename, we therefore
miss the inactive time for an overwritten node. This bounds us to give up
PUFFS_KFLAG_IAONDEMAND.
= Removed files =
- forbid most operations on a removed node, return ENOENT
- setback PUFFS_SETBACK_NOREF_N1 at inactive stage to cause removed
file reclaim
= Misc =
- Update outdated ARGSUSED for lint
- Fix a memory leak (puffs_pn_remove instead of puffs_pn_put)
- Do not use PUFFS_FLAG_BUILDPATH except for debug output. It makes the
lookup code much simplier.
