fs: cifs: mute -Wunused-const-variable message

2019-10-07T03:04:35Z

After 'Initial git repository build' commit, 'mapping_table_ERRHRD' variable has not been used. So 'mapping_table_ERRHRD' const variable could be removed to mute below warning message: fs/cifs/netmisc.c:120:40: warning: unused variable 'mapping_table_ERRHRD' [-Wunused-const-variable] static const struct smb_to_posix_error mapping_table_ERRHRD[] = { ^ Signed-off-by: Austin Kim Signed-off-by: Steve French

fs: cifs: Initialize filesystem timestamp ranges

2019-08-30T14:27:18Z

Fill in the appropriate limits to avoid inconsistencies in the vfs cached inode times when timestamps are outside the permitted range. Also fixed cnvrtDosUnixTm calculations to avoid int overflow while computing maximum date.

cifs: use timespec64 internally

2018-08-07T19:15:41Z

In cifs, the timestamps are stored in memory in the cifs_fattr structure, which uses the deprecated 'timespec' structure. Now that the VFS code has moved on to 'timespec64', the next step is to change over the fattr as well. This also makes 32-bit and 64-bit systems behave the same way, and no longer overflow the 32-bit time_t in year 2038.

cifs: small underflow in cnvrtDosUnixTm()

2017-05-02T19:57:34Z

January is month 1. There is no zero-th month. If someone passes a zero month then it means we read from one space before the start of the total_days_of_prev_months[] array. We may as well also be strict about days as well. Fixes: 1bd5bbcb6531 ("[CIFS] Legacy time handling for Win9x and OS/2 part 1") Signed-off-by: Dan Carpenter Signed-off-by: Steve French

Fix signed/unsigned pointer warning

[CIFS] Fix setting time before epoch (negative time values)

2014-09-14T22:06:36Z

xfstest generic/258 sets the time on a file to a negative value (before 1970) which fails since do_div can not handle negative numbers. In addition 'normal' division of 64 bit values does not build on 32 bit arch so have to workaround this by special casing negative values in cifs_NTtimeToUnix Samba server also has a bug with this (see samba bugzilla 7771) but it works to Windows server.

cifs: change ERRnomem error mapping from ENOMEM to EREMOTEIO

2013-11-11T22:33:25Z

Sometimes, the server will report an error that basically indicates that it's running out of resources. These include these under SMB1: NT_STATUS_NO_MEMORY NT_STATUS_SECTION_TOO_BIG NT_STATUS_TOO_MANY_PAGING_FILES ...and this one under SMB2: STATUS_NO_MEMORY Currently, this gets mapped to ENOMEM by the client, but that's confusing as an ENOMEM error is typically an indicator that the client is out of memory. Change these errors to instead map to EREMOTEIO to indicate that the problem is actually server-side and not on the client.
