Qhov tsis txaus ntseeg nyob hauv lub peev xwm ntawm tus neeg tawm tsam tej thaj chaw deb kom nkag mus rau cov npe sab nraud NFS cov ntawv xa tawm los ntawm kev hu rau READDIRPLUS ntawm .. hauv paus export directory.
Qhov tsis zoo tau raug kho nyob rau hauv kernel 23, tso tawm rau Lub Ib Hlis 5.10.10, nrog rau tag nrho lwm cov kev txhawb nqa ntawm kernels hloov tshiab rau hnub ntawd:

nfsd4: readdirplus yuav tsum tsis txhob xa niam txiv ntawm export
commit 51b2ee7d006a736a9126e8111d1f24e4fd0afaa6 upstream.
Yog hais tias koj export ib subdirectory ntawm ib tug filesystem, READDIRPLUS ntawm lub hauv paus
ntawm qhov kev xa tawm yuav xa rov qab cov ntaub ntawv ntawm niam txiv nrog ".."
nkag.
Lub filehandle yog xaiv tau, yog li cia peb tsis rov qab cov ntaub ntawv rau
".." Yog tias peb nyob ntawm lub hauv paus ntawm kev xa tawm.
Nco ntsoov tias thaum tus neeg siv tau kawm ib daim ntawv tuav tawm sab nraud ntawm kev xa tawm,
lawv tuaj yeem nkag mus rau qhov seem ntawm kev xa tawm siv kev tshawb nrhiav ntxiv.
Txawm li cas los xij, nws kuj tsis yooj yim rau kwv yees filehandles sab nraud
lub export. Yog li exporting subdirectory ntawm ib tug filesystem yuav tsum
suav tias yog sib npaug los muab kev nkag mus rau tag nrho cov filesystem. Rau
zam kev tsis meej pem, peb pom zoo tsuas yog exporting tag nrho cov ntaub ntawv.
