Replace multiple, consecutive "\" characters prior to other processing involving "\" characters. This fixes an issue where "\\..\\..", "//..//..", and similar input paths are not cleaned properly.

2018-10-12MdePkg-BaseLib: Fix PathCleanUpDirectories() error involving "\..\.."Jim.Dailey@dell.com1-1/+4
MdePkg-BaseLib: Fix PathCleanUpDirectories() error involving "\..\.." The loop that removes "xxxx\..\" errs when multiple "\.." sequences are in the path. Before this change the code would modify a path like "FS0:\efi\tools\..\.." to "FS0:\efi\\.." and then to "FS0:\efi\", but the correct path is "FS0:\". You can test the effect of this change in the shell by setting the current directory to something like FS0:\efi\boot and then executing the command "ls ..\..". Before the change you will see the files in the FS0:\efi directory; after the change, you will see the files in the root directory of FS0:.

2017-09-21MdePkg/BaseLib: Avoid reading content beyond string boundaryHao Wu1-2/+2
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=705 As mentioned in the above Bugzilla link by Steven, within the function PathCleanUpDirectories(), when executing command: "cd ." under Shell, the input parameter 'Path' string will have string length less than 2. Hence, it is possible for the below statement: "if (StrCmp (Path + StrLen (Path) - 2, L"\\.") == 0) {" to read contents before the string boundary. This commit adds additional checks to avoid this.

2016-11-21MdePkg BaseLib: API PathRemoveLastItem not handle root paths properlyHao Wu1-4/+5
https://bugzilla.tianocore.org/show_bug.cgi?id=239 When the input path for API PathRemoveLastItem() is a root path like 'fs0:\', the API will return TRUE (indicating a directory or file was removed from the path) and modifies the path to 'fs0:'. In fact, there's no directory or file removed in the above case. This commit adds additional check to resolve this issue and modifies the API's description to make it more straightforward.

2016-08-10MdePkg: Enhance PathRemoveLastItem() to support "FS0:File.txt"Ruiyu Ni1-2/+3
The original implementation only looks for very last backslash and removes the string after that. But when the path is like "FS0:File.txt" which doesn't contain backslash, the function cannot work well. The patch enhances the code to look for very last backslash or colon to support the path which doesn't contain backslash.
