15 years agoWhen cfq I/O scheduler is selected, get_request() in __make_request() calls
Kiyoshi Ueda [Fri, 17 Jun 2005 14:15:10 +0000]
When cfq I/O scheduler is selected, get_request() in __make_request() calls
__cfq_get_queue().  __cfq_get_queue() finds an existing queue (struct
cfq_queue) of the current process for the device and returns it.  If it's not
found, __cfq_get_queue() creates and returns a new one if __cfq_get_queue() is
called with __GFP_WAIT flag, or __cfq_get_queue() returns NULL (this means that
get_request() fails) if no __GFP_WAIT flag.

On the other hand, in __make_request(), get_request() is called without
__GFP_WAIT flag at the first time.  Thus, the get_request() fails when there is
no existing queue, typically when it's called for the first I/O request of the
process to the device.

Though it will be followed by get_request_wait() for general case,
__make_request() will just end the I/O with an error (EWOULDBLOCK) when the
request was for read-ahead.

[PATCH] sbp2 slab corruption fix

This fixed a problem that showed up in the Fedora development tree a few
weeks before the Fedora Core 4 release, initially as slab corruption, later
as hard crashes on boot up, when slab debugging was disabled for the
release.  More details on the history at
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=158424

The problem is caused by sbp2's use of scsi_host->hostdata[0] to hold a
scsi_id, without explicitly requesting space for it.  Since hostdata is
declared as a zero-sized array, we don't get any such space by default, so
it must be explicitly requested.  The patch below implements just that.

[PATCH] Fix PCI BAR size interpretation on 64-bit arches

On 64-bit machines, PCI_BASE_ADDRESS_MEM_MASK and other mask constants
passed to pci_size() are 64-bit (for example ~0x0fUL).  However, pci_size
does comparisons between the u32 arguments and the mask, which will fail
even though any result from pci_size is still just 32-bit.

Changing the mask argument to u32 seems the obvious thing to do, since all
arithmetic in the function is 32-bit and having a larger mask makes no
sense.

This triggered on a PPC64 system here where an adapter (VGA, as it
happened) had a memory region base of 0xfe000000 and a sz of the same,
matching the if (max == maxbase ...) test at the bottom of pci_size but
failing the mask comparison.  Quite a corner case which I guess explains
why we haven't seen it until now.

[IPV4]: Sysctl configurable icmp error source address.

This patch alows you to change the source address of icmp error
messages. It applies cleanly to 2.6.11.11 and retains the default
behaviour.

In the old (default) behaviour icmp error messages are sent with the ip
of the exiting interface.

The new behaviour (when the sysctl variable is toggled on), it will send
the message with the ip of the interface that received the packet that
caused the icmp error. This is the behaviour network administrators will
expect from a router. It makes debugging complicated network layouts
much easier. Also, all 'vendor routers' I know of have the later
behaviour.

15 years ago[IPv6] Don't generate temporary for TUN devices
Rémi Denis-Courmont [Mon, 13 Jun 2005 22:01:34 +0000]
[IPv6] Don't generate temporary for TUN devices

Userland layer-2 tunneling devices allocated through the TUNTAP driver
(drivers/net/tun.c) have a type of ARPHRD_NONE, and have no link-layer
address. The kernel complains at regular interval when IPv6 Privacy
extension are enabled because it can't find an hardware address :

Dec 29 11:02:04 auguste kernel: __ipv6_regen_rndid(idev=cb3e0c00):
cannot get EUI64 identifier; use random bytes.

IPv6 Privacy extensions should probably be disabled on that sort of
device. They won't work anyway. If userland wants a more usual
Ethernet-ish interface with usual IPv6 autoconfiguration, it will use a
TAP device with an emulated link-layer  and a random hardware address
rather than a TUN device.

As far as I could fine, TUN virtual device from TUNTAP is the very only
sort of device using ARPHRD_NONE as kernel device type.

|BUG: using smp_processor_id() in preemptible [00000001] code: httpd/30137
|caller is icmpv6_send+0x23/0x540

This is because of icmpv6_socket, which is the only one user of

The ARM generic Kconfig filters out IDE options ... except for

This adds one general case to the systems that will offer IDE options:
kernels with PCMCIA support, which probably want to use IDE to access
CompactFlash cards.  This might allow many (most?) of the other cases
to disappear, for systems that only see IDE hardware through CF cards.
Right now this one patch is used to gate access to CF cards, including
MicroDrives, for both omap_cf and at91_cf drivers.

Benjamin Herrenschmidt [Fri, 10 Jun 2005 04:19:02 +0000]
[PATCH] ppc32: Fix nasty sleep/wakeup problem

Despite all the care lately in making the powermac sleep/wakeup as
robust as possible, there is still a nasty related to the use of cpufreq
on PMU based machines.  Unfortunately, it affects paulus old powerbook
so I have to fix it :)

We didn't manage to understand what is precisely going on, it leads to
memory corruption and might have to do with RAM not beeing properly
refreshed when a cpufreq transition is done right before the sleep.

The best workaround (and less intrusive at this point) we could come up
with is included in this patch.  We basically do _not_ force a switch to
high speed on suspend anymore (that is what is causing the problem) on
those machines.  We still force a speed switch on wakeup (since we don't
know what speed we are coming back from sleep at, and that seems to work
fine).

Since, during this short interval, the actual CPU speed might be
incorrect, we also hack around by multiplying loops_per_jiffy by 2 (max
speed factor on those machines) during early wakeup stage to make sure
udelay's during that time aren't too short.

For after 2.6.12, we'll change udelay implementation to use the CPU
timebase (which is always constant) instead like we do on ppc64 and thus
get rid of all those problems.

Michael Ellerman [Thu, 9 Jun 2005 19:36:33 +0000]
[PATCH] iseries_veth: Supress spurious WARN_ON() at module unload

My patch from a few weeks back (now in mainline), called "Cleanup skbs to
prevent unregister_netdevice() hanging", can cause our TX timeout code to
fire on machines with lots of VLANs (because it takes > 2 seconds between
when we stop the queues and when we're finished stopping the connections).

When that happens the TX timeout code freaks out and does a WARN_ON()
because as far as it's concerned there shouldn't be a TX timeout happening,
which is fair enough.

I have a "proper" fix for this, which is to a) do refcounting on
connections and b) implement a proper ack timer so we don't keep unacked
skbs lying around for ever.  But for 2.6.12 I propose just supressing the
WARN_ON().  Users will still see the "NETDEV WATCHDOG" warning, but that's
not nearly as bad as a WARN_ON() which users interpret as an Oops.

Ian Abbott [Thu, 2 Jun 2005 09:34:11 +0000]
[PATCH] USB: ftdi_sio: avoid losing received data in tty-ldisc

ftdi_sio: Avoid losing bytes at tty-ldisc.

This patch was originally developed by Daniel Smertnig.  I
(Ian Abbott) made a few changes.  It has been tested by both
Daniel and I, at least for raw, non-canonical receive data
processing.

Here is Daniel's original description of the patch:

===
During a project in which I was using a FTDI 232BM to
transmit data at relative high speeds (625kBit/s), I
noticed a problem where data was lost even if flow
control was enabled: The FTDI-Driver receives 512 Bytes
of data over USB at a time, which consists of 8 64-Byte
packets. Subtracting the 2 bytes of status information
included in each packet this gives 496 "real" data
bytes per read.

This data is passed (indirectly, via the flip buffers)
to the tty line discipline which takes care of
throttling when there the free buffer space reaches
TTY_THRESHOLD_THROTTLE (128). Because the FTDI driver
processes up to 496 bytes at a time, throttling won't
happen in time and the line discipline will discard the
remaining bytes.

To avoid this the patch passes data in 62-byte blocks
to the tty layer and checks the available space in the
ldisc-buffers. If there isn't enough free space,
processing the rest of the data is delayed using a
workqueue.

Note: The original problem should be easily
reproducible with a userspace program which does slow &
small reads.

[PATCH] USB: fix ub issues

This smoothes two imperfections:
- Increase number of LUNs per device from 4 to 9. The best solution
  would be to remove this limit altogether, but that has to wait until
  the time when more than 26 hosts are allowed.
- Replace mdelay with msleep in a probing routine.

[PATCH] sg traverse fix for __atapi_pio_bytes()

Problem:
Incorrect md5sum when using ATAPI PIO mode to verify a distro CD.

Root cause:  sg traverse problem.
In __atapi_pio_bytes(), if qc->cursg++ is increased and "goto
next_page" is executed, then sg is not updated to the new qc->cursg
and the old sg is overwritten with the new data.

Changes:
- Replace "goto next_page" with "goto next_sg" to make sg updated.

[PATCH] ppc64: Fix PER_LINUX32 behaviour

This patch fixes some bugs in the ppc64 PER_LINUX32 implementation,
noted by Juergen Kreileder:

* uname(2) doesn't respect PER_LINUX32, it returns 'ppc64' instead of 'ppc'
* Child processes of a PER_LINUX32 process don't inherit PER_LINUX32

Along the way I took the opportunity to move things around so that
sys_ppc32.c only has 32-bit syscall emulation functions and to remove
the obsolete "fakeppc" command line option.

15 years ago[PATCH] ia64: fix floating-point preemption problem
Peter Chubb [Wed, 8 Jun 2005 22:50:20 +0000]
[PATCH] ia64: fix floating-point preemption problem

There've been reports of problems with CONFIG_PREEMPT=y and the high
floating point partition.  This is caused by the possibility of preemption
and rescheduling on a different processor while saving or restioirng the
high partition.

The only places where the FPU state is touched are in ptrace, in
switch_to(), and where handling a floating-point exception.  In switch_to()
preemption is off.  So it's only in trap.c and ptrace.c that we need to
prevent preemption.

Here is a patch that adds commentary to make the conditions clear, and adds
appropriate preempt_{en,dis}able() calls to make it so.  In trap.c I use
preempt_enable_no_resched(), as we're about to return to user space where
the preemption flag will be checked anyway.
