Subject: eventfd: Implement eventfd2 and fix eventfd

eventfd: evntfd assumes to take two arguments instead it

should be one evntfd expects two therefore implement both syscalls with

correct parameters

Subject: pread/pwrite: backport fix
|
||||
|
||||
pread/pwrite syscalls has been renamed to pread64/pwrite in 2.6 kernel.
|
||||
|
||||
There was a fallback function using lseek for kernels who did not have
|
||||
this syscall (pre 2.1.60). This is broken in many ways.
|
||||
|
||||
uclibc have been using the broken fallback due to they forgot to rename
|
||||
pread syscall.
|
||||
|
||||
This got detected with git-1.7.11 which introduced threaded index-pack
|
||||
which broke in similar ways a windows (msys).
|
||||
|
||||
This issue in uclibc have been reported upstream and fixed in git master
|
||||
so this patch does not need to be upstreamed. It might be an idea to
|
||||
backport it properly for 0.9.33 branch though.

Subject: pread/pwrite: backport fix
|
||||
|
||||
pread/pwrite syscalls has been renamed to pread64/pwrite in 2.6 kernel.
|
||||
|
||||
There was a fallback function using lseek for kernels who did not have
|
||||
this syscall (pre 2.1.60). This is broken in many ways.
|
||||
|
||||
uclibc have been using the broken fallback due to they forgot to rename
|
||||
pread syscall.
|
||||
|
||||
This got detected with git-1.7.11 which introduced threaded index-pack
|
||||
which broke in similar ways a windows (msys).
|
||||
|
||||
This issue in uclibc have been reported upstream and fixed in git master
|
||||
so this patch does not need to be upstreamed. It might be an idea to
|
||||
backport it properly for 0.9.33 branch though.

Subject: pread/pwrite: backport fix
|
||||
|
||||
pread/pwrite syscalls has been renamed to pread64/pwrite in 2.6 kernel.
|
||||
|
||||
There was a fallback function using lseek for kernels who did not have
|
||||

|
||||
|
||||
uclibc have been using the broken fallback due to they forgot to rename
|

pread syscall.
|
||||
|
||||
This got detected with git-1.7.11 which introduced threaded index-pack
|
||||
which broke in similar ways a windows (msys).
|
||||
|
||||
This issue in uclibc have been reported upstream and fixed in git master
|

so this patch does not need to be upstreamed. It might be an idea to
|
||||
backport it properly for 0.9.33 branch though.

Subject: pread/pwrite: backport fix
|
||||
|
||||
pread/pwrite syscalls has been renamed to pread64/pwrite in 2.6 kernel.
|
||||
|
||||
There was a fallback function using lseek for kernels who did not have
|
||||
this syscall (pre 2.1.60). This is broken in many ways.
|
||||
|
||||
uclibc have been using the broken fallback due to they forgot to rename
|
||||
pread syscall.
|
||||
|
||||
This got detected with git-1.7.11 which introduced threaded index-pack
|
||||
which broke in similar ways a windows (msys).
|
||||
|
||||
This issue in uclibc have been reported upstream and fixed in git master
|
||||
so this patch does not need to be upstreamed. It might be an idea to
|
||||
backport it properly for 0.9.33 branch though.

Subject: pread/pwrite: backport fix
|

|

pread/pwrite syscalls has been renamed to pread64/pwrite in 2.6 kernel.
|
||||
|
||||
There was a fallback function using lseek for kernels who did not have
|
||||

|
||||
|
||||
uclibc have been using the broken fallback due to they forgot to rename

pread syscall.
|

|
||||
This got detected with git-1.7.11 which introduced threaded index-pack
|
||||
which broke in similar ways a windows (msys).
|
||||
|
||||
This issue in uclibc have been reported upstream and fixed in git master
|

so this patch does not need to be upstreamed. It might be an idea to
|
||||
backport it properly for 0.9.33 branch though.

Subject: pread/pwrite: backport fix
|
||||
|
||||
pread/pwrite syscalls has been renamed to pread64/pwrite in 2.6 kernel.
|
||||
|
||||
There was a fallback function using lseek for kernels who did not have
|
||||
this syscall (pre 2.1.60). This is broken in many ways.
|
||||
|
||||
uclibc have been using the broken fallback due to they forgot to rename
|
||||
pread syscall.
|
||||
|
||||
This got detected with git-1.7.11 which introduced threaded index-pack
|
||||
which broke in similar ways a windows (msys).
|
||||
|
||||
This issue in uclibc have been reported upstream and fixed in git master
|
||||
so this patch does not need to be upstreamed. It might be an idea to
|
||||
backport it properly for 0.9.33 branch though.

Subject: eventfd: Implement eventfd2 and fix eventfd
|

|

eventfd: evntfd assumes to take two arguments instead it
|

should be one evntfd expects two therefore implement both syscalls with
|

correct parameters
|

Thanks Eugene Rudoy for reporting it and also providing the patch

Subject: pread/pwrite: backport fix
|
||||
|
||||
pread/pwrite syscalls has been renamed to pread64/pwrite in 2.6 kernel.
|
||||
|
||||
There was a fallback function using lseek for kernels who did not have
|
||||
this syscall (pre 2.1.60). This is broken in many ways.
|
||||
|
||||
uclibc have been using the broken fallback due to they forgot to rename
|
||||
pread syscall.
|
||||
|
||||
This got detected with git-1.7.11 which introduced threaded index-pack
|
||||
which broke in similar ways a windows (msys).
|
||||
|
||||
This issue in uclibc have been reported upstream and fixed in git master
|
||||
so this patch does not need to be upstreamed. It might be an idea to
|
||||
backport it properly for 0.9.33 branch though.
