PATCH v4 3/12 arch: Use asm-generic/socket.h when possible
In reply to Deepa DinamaniMany architectures maintain an arch specific copy of the file even though there are no differences with the asm-generic one. Allow these architectures to use the generic one instead.

PATCH v4 4/12 sockopt: Rename SO_TIMESTAMP* to SO_TIMESTAMP*_OLD
In reply to Deepa DinamaniSO_TIMESTAMP, SO_TIMESTAMPNS and SO_TIMESTAMPING options, the way they are currently defined, are not y2038 safe. Subsequent patches in the series add new y2038 safe versions of these options which provide 64 bit timestamps on all architectures uniformly.
Hence, rename existing options with OLD tag suffixes.
Also note that kernel will not use the untagged SO_TIMESTAMP* and SCM_TIMESTAMP* options internally anymore.

PATCH v4 5/12 arch: sparc: Override struct __kernel_old_timeval
In reply to Deepa Dinamanistruct __kernel_old_timeval is supposed to have the same layout as struct timeval. But, it was inadvarently missed that __kernel_suseconds has a different definition for sparc64.
Provide an asm-specific override that fixes it.

PATCH v4 11/12 socket: Rename SO_RCVTIMEO/ SO_SNDTIMEO with _OLD suffixes
In reply to Deepa DinamaniSO_RCVTIMEO and SO_SNDTIMEO socket options use struct timeval as the time format. struct timeval is not y2038 safe. The subsequent patches in the series add support for new socket timeout options with _NEW suffix that will use y2038 safe data structures. Although the existing struct timeval layout is sufficiently wide to represent timeouts, because of the way libc will interpret time_t based on user defined flag, these new flags provide a way of having a structure that is the same for all architectures consistently.
Rename the existing options with _OLD suffix forms so that the right option is enabled for userspace applications according to the architecture and time_t definition of libc.

v4 cover net: y2038-safe socket timestamps
The series introduces new socket timestamps that are y2038 safe.
The time data types used for the existing socket timestamp
options: SO_TIMESTAMP, SO_TIMESTAMPNS and SO_TIMESTAMPING are not y2038 safe. The series introduces SO_TIMESTAMP_NEW, SO_TIMESTAMPNS_NEW and SO_TIMESTAMPING_NEW to replace these. These new timestamps can be used on all architectures.
The alternative considered was to extend the sys_setsockopt() by using the flags. We did not receive any strong opinions about either of the approaches. Hence, this was chosen, as glibc folks preferred this.
The series does not deal with updating the internal kernel socket calls like rxrpc to make them y2038 safe. This will be dealt with separately.
Note that the timestamps behavior already does not match the man page specific behavior:
SIOCGSTAMP
This ioctl should only be used if the socket option SO_TIMESTAMP
is not set on the socket. Otherwise, it returns the timestamp of the last packet that was received while SO_TIMESTAMP was not set, or it fails if no such packet has been received, (i.e., ioctl(2) returns -1 with errno set to ENOENT).
The recommendation is to update the man page to remove the above statement.
The overview of the socket timestamp series is as below:
1. Delete asm specific socket.h when possible.
2. Support SO/SCM_TIMESTAMP* options only in userspace.
3. Rename current SO/SCM_TIMESTAMP* to SO/SCM_TIMESTAMP*_OLD.
3. Alter socket options so that SOCK_RCVTSTAMPNS does not rely on SOCK_RCVTSTAMP.
4. Introduce y2038 safe types for socket timestamp.
5. Introduce new y2038 safe socket options SO/SCM_TIMESTAMP*_NEW.
6. Intorduce new y2038 safe socket timeout options.
Changes since v3:
* Rebased onto net-next and fixups as per review comments
* Merged the socket timeout series
* Integrated Arnd's patch to simplify compat handling of timeout syscalls
Changes since v2:
* Removed extra functions to reduce diff churn as per code review
Changes since v1:
* Dropped the change to disentangle sock flags
* Renamed sock_timeval to __kernel_sock_timeval
* Updated a few comments
* Added documentation changes

PATCH v4 2/12 socket: move compat timeout handling into sock.c
In reply to Deepa DinamaniFrom: Arnd Bergmann <[email protected]>
This is a cleanup to prepare for the addition of 64-bit time_t in O_SNDTIMEO/O_RCVTIMEO. The existing compat handler seems unnecessarily complex and error-prone, moving it all into the main setsockopt()/getsockopt() implementation requires half as much code and is easier to extend.
32-bit user space can now use old_timeval32 on both 32-bit and 64-bit machines, while 64-bit code can use __old_kernel_timeval.

PATCH v4 6/12 socket: Use old_timeval types for socket timestamps
In reply to Deepa DinamaniAs part of y2038 solution, all internal uses of struct timeval are replaced by struct __kernel_old_timeval and struct compat_timeval by struct old_timeval32. Make socket timestamps use these new types.
This is mainly to be able to verify that the kernel build is y2038 safe when such non y2038 safe types are not supported anymore.

PATCH v4 7/12 socket: Add struct __kernel_sock_timeval
In reply to Deepa DinamaniThe new type is meant to be used as a y2038 safe structure to be used as part of cmsg data.
Presently the SO_TIMESTAMP socket option uses struct timeval for timestamps. This is not y2038 safe.
Subsequent patches in the series add new y2038 safe socket option to be used in the place of SO_TIMESTAMP_OLD. struct __kernel_sock_timeval will be used as the timestamp format at that time.
struct __kernel_sock_timeval also maintains the same layout across 32 bit and 64 bit ABIs.

The series introduces new socket timestamps that are y2038 safe.
The time data types used for the existing socket timestamp
options:SO_TIMESTAMP,SO_TIMESTAMPNSandSO_TIMESTAMPINGare not y2038 safe. The series introducesSO_TIMESTAMP_NEW,SO_TIMESTAMPNS_NEWandSO_TIMESTAMPING_NEWto replace these. These new timestamps can be used on all architectures.The alternative considered was to extend the
sys_setsockopt()by using the flags. We did not receive any strong opinions about either of the approaches. Hence, this was chosen, as glibc folks preferred this.The series does not deal with updating the internal kernel socket calls like rxrpc to make them y2038 safe. This will be dealt with separately.
Note that the timestamps behavior already does not match the man page specific behavior:
SIOCGSTAMP
This ioctl should only be used if the socket optionSO_TIMESTAMP
is not set on the socket. Otherwise, it returns the timestamp of the last packet that was received whileSO_TIMESTAMPwas not set, or it fails if no such packet has been received, (i.e., ioctl(2) returns -1 with errno set to ENOENT).The recommendation is to update the man page to remove the above statement.
The overview of the socket timestamp series is as below:
1. Delete asm specificsocket.hwhen possible.
2. Support SO/SCM_TIMESTAMP* options only in userspace.
3. Rename current SO/SCM_TIMESTAMP* to SO/SCM_TIMESTAMP*_OLD.
3. Alter socket options so thatSOCK_RCVTSTAMPNSdoes not rely onSOCK_RCVTSTAMP.
4. Introduce y2038 safe types for socket timestamp.
5. Introduce new y2038 safe socket options SO/SCM_TIMESTAMP*_NEW.
6. Intorduce new y2038 safe socket timeout options.Changes since v3:
* Rebased onto net-next and fixups as per review comments
* Merged the socket timeout series
* Integrated Arnd's patch to simplify compat handling of timeout syscallsChanges since v2:
* Removed extra functions to reduce diff churn as per code reviewChanges since v1:
* Dropped the change to disentangle sock flags
* Renamedsock_timevalto__kernel_sock_timeval
* Updated a few comments
* Added documentation changesArnd Bergmann (1):

The sock_get_timeout() should actually be passed in v instead of optval. This seems like a typo. I will post an update to fix this.
So these are needed.
Thanks,
