Release Notes For Linux 2.0.36
- Large Memory
- Linux 2.0.36 uses the newer bios calls to automatically size memory
above 64Mbytes, where supported by the BIOS. A maximum of just under 1Gig
is available for Linux 2.0.36.
- Processes issuing a readv or writev to a device that did not have
the relevant read/write operation could cause an Oops and potentially a
- UDMA Drives
- Report Bad CRC (cable errors) as a cable error. Handling of such
errors was correct.
- TCP spoofing
- A very obscure TCP spoofing attack is now blocked. As far as we know
only the lab who discovered it are aware of the problem, and no active
use of such attack has ever been seen on the internet.
- A pair of SMP bugs have been fixed. The first resolves the instabilities
with 3+ CPU machines, the second resolves an IRQ forwarding problem that
caused "Re-entering IRQ" hangs. SMP should be significantly more stable on
2.0.36 than previous 2.0.x releases.
- pipe syscall error
- The pipe call could return ENFILE not -1 and errno= -ENFILE. Fixed.
- The 2.0.36 kernel contains the 5.0.20 release of the AIC7xxx driver.
This should cure most of the remaining problems with the older chipsets.
Users with the latest AIC7xxx devices will have to wait for the next driver
version to become available or try the beta test driver.
- Procfs permissions fix
- A process with root file rights can now read all /proc files.
- Daylight Savings in SMB
- The SMB file system honours daylight savings time.
- EATA SCSI/Ultrastor 14f/34f
- Reverse scan order support and configurable extended geometry. Increased
the busy timeout.
- IN2000 SCSI
- This driver now works in SMP mode.
- Build fixes
- Use relative paths for sound, remove trampoline.hex on a make clean,
support the newer versioned symbols as part of a multi object file module.
- Oops handling
- A small fencepost error in Oops handling on syscall return has been
- TLan 1.0
- The Thunderlan driver has been updated to the 1.0 release.
- Delay loops
- The delay loop code has been modified to eliminate most of the remaining
cache/branch prediction and other variants to its performance.
- 5.25" floppy
- An incorrect floppy table entry has been altered, and a potential
crash on unload fixed.
- Iomega ZIP driver
- Handle 23.D firmware funnies.
- Cyclades Serial
- Upgraded driver from vendor, with assorted bugs fixed.
- Printer Driver
- The correction in the printer handling upset the Epson Stylus 800. The
driver know has a LPSTRICT option that can be set for printers that need
absolute strict NBUSY handling.
- Beeper gets stuck
- The case where the beeper decides to beep forever has been cured.
- 3c509 ethernet
- Upgraded to v1.16. Fixes ID port clash with sound cards, waiting for
discard messages and recovers faster from transmit errors.
- 3c59x driver
- Updated 3c59x ethernet driver. This should cure the skb_push panics some
people saw with 3c59x/3c90x drivers under load.
- Lance driver
- Module unload bugs in the lance driver have been fixed.
- Plip driver
- Messages without severity levels now have appropriate levels.
- Allow the use of DMA 0 on newer motherboards.
- SHM swap off
- A case where the machine might crash when turning swapping off has been
- MMAP security
- Linux did not allow a writable mmap of an append only file. It did however
allow a readonly mmap of such a file then an mprotect. Fixed.
- NAKAMICH MJ-5.16S
- This SCSI device has been added to the blacklist.
- Single lun blacklisting
- A bug in the single lun blacklisting has been fixed.
- SCSI CAM division by zero
- A corrupt geometry could cause the kernel to divide by zero and crash.
- Sound blaster
- Don't report a DMA channel 0 for the MPU
- If there are no synths or midi devices do not lock the sequencer busy
- Fix a small glitch in the directory hash.
- Fix a fencepost error in the iso fs size checks.
- Vfat fs
- Disallow periods at the end of names.
- NFS file system
- Support FIFO's over NFS. Handle kill of nfsiod for module unload.
- NFS root
- IFF_MULTICAST could be incorrectly not set.
- Non modular soundmodem/baycom
- These devices only worked as modules. They now work compiled in.
- Memory leak in networking
- A very obscure leak in the networking code has been fixed.
- TCP select
- TCP select for urgent data now has correct semantics. Previously it
could do the wrong thing.
- TCP SIGIO
- SIGIO on an incoming connection is now correctly issued on the
completion of the three way handshake.
- Crash on powerdown
- When APM was enabled but not present, and APM power off was enabled the
kernel could crash at the end of the shutdown sequence.
- Alpha NTP
- The Alpha uses a 1024Hz clock and this threw off some values used for NTP
- The Isdn4linux layer is signifcantly upgraded. The new driver set adds
support for the Teles 16.3c, Teles PCI, Teles S0Box, Creatix S0Box,
Compaq ISDN S0 ISA, ELSA Quickstep 1000PCI, Elsa Quickstep 3000, Elsa
Quickstep 3000PCI, Eicon.Diehl Diva 2.0 ISA/PCI (not Pro), Eicon.Diehl
Diva Piccola, AsusCom ISDNLink 128K, Dynalink IS64PH, HFC-2BS0 based cards,
Sedlbauer Speed Card(Speed win, teledat 100), Sedlbauer Speed Star PCMCIA,
USR Sportster Internal TA, ITH MIC 16 ISA, Traverse NETjet PCI, Niccy
- ICP Vortex
- The ICP vortex driver supports the latest ICP raid cards up to and including
- AMI MegaRAID
- Driver support for the AMI MegaRAID SCSI controller.
- The shaper device provides a simple traffic limiting driver for Linux
2.0.x. For full traffic shaping watch for Linux 2.2 coming soon..
- The tulip driver has been upgraded to 0.89H which should also support
the clone PNIC and MXIC tulip devices.
- Extended CPUID/Chip identification
- The Cyrix/AMD extended CPUID mode is supported. Cyrix processors are
identified even when CPUID is not available. The Intel Celeron Mendocino is
recognized. K6's with the random oops bug are normally now detected. The
K6 cpu deadlock problem isn't detected as we know no way to check for it except
to try it.
- Multi-Tech driver
- Driver for multi-tech 4/8 port modem and serial cards.(Experimental).
- The Compaq LTE should now be recognized (experimental)
- Intel 440GX
- The 440GX chipset is known to the PCI data tables.
- NVidia/SGS Thomson is known to the PCI data tables.
- SCSI medium changers
- These are no long reported as unknown device types.
- ROSE networking
- The ROSE network layer has been updated.
- Bigger system call table
- To support add ons that use syscalls in the new range.
- Hooks for dumping
- Kernel hooks for optional threaded core dump module.
